What Is Amazon SQS?

Caroline — Fri, 10 Jun 2022 21:14:26 +0000

When two services needed to communicate with one another in the past, one service would make an api call to notify the other service that something had changed or taken some action.

With Amazon Simple Queue Service(SQS), the event or notification-producing service can asynchronously notify the consumer that something has changed in its system, allowing for a very clean decoupling of these two services.

Types Of SQS

There are two types of SQS:

Standard Queue
FIFO Queue

Standard Queue

Standard Queue has an unlimited throughput. What this means is that there's an infinite processing rate.

You can perform nearly an unlimited number of transactions per second.

Delivery Indifference

A message is delivered at least once, but occasionally more than one copy of a message is delivered.

Processing Duplicate

Occasionally more than one copy of a message is delivered.

They might also be delivered in an order different from which they were sent.

FIFO Queue

First and foremost, FIFO Queue stands for first in, first out. It operates in the same manner as its name. What comes in first is processed first.

Processing In Exact Order

Messages are sent and received in strict chronological order.

Messages are also delivered in sequence, so there is no possibility of out-of-order processing.

There is a tps (transactions per second) limit, so there is no unlimited throughput. You do have a capt with a maximum value of 300 tps.

However, if you use batching, you can publish to SQS with up to 10 messages in a batch and only use one api operation.

As a result, you can publish 3000 tps instead of 300 if you use ten messages per batch.

The key advantage of Amazon SQS is that it allows for asynchronous message-based communication, which makes it better than API calls.

SQS was one of the initial services offered by Amazon Web Services. It was first released as a beta in 2004 and then as a complete release in 2006.

AWS Lambda: Reduce IT Maintenance Costs And Simplify Scalability

Caroline — Sat, 04 Jun 2022 05:56:28 +0000

The serverless architecture strategy using the AWS lambda function service. This architecture is ideal for "Micro-Services" software development techniques.

What Is Serverless Architecture?

The term "serverless architecture" refers to a cloud computing model where developers can create and run applications without managing the infrastructure.

The serverless model is distinguished by its simplicity. The developer only needs to supply his code. The cloud service provider handles everything else.

The "serverless" model disregards the IT infrastructure. The technical teams are no longer constrained by infrastructure constraints and can focus on product development.

The developer is in charge of developing his function(s). The remainder is up to the cloud service provider. There are rules to follow to host an application in a serverless architecture.

We'll sneak peek into how to think about your serverless code and how AWS makes it possible to implement it with its AWS Lambda service.

Working On Your Serverless Code

The first principle of a serverless function is designed to perform a single and distinct task.

Therefore, a function can only have an entry point and a response.

As a result, you will need to divide your application into functions. The term "serverless" is frequently used to refer to the "Function as a Service" (FaaS) methodology. You can associate a type of event with each function. For example, if the function is requested via HTTP. The request causes the code and thus the function to be executed.

One should note that the triggering events can be varied, such as adding a file to a storage space or creating a new entry in a database.

You can run an entire application with multiple layers, models, and services in a single lambda!

Remember that a function can only have one entry point and one response type.

Lambda Functions to Implement a Serverless Architecture

Lambda runs your application code on a high-availability compute infrastructure and manages all compute resources, including server and operating system maintenance, capacity sizing and scaling, automatic code and security patch deployment, and code monitoring and logging.

The number of servers, their power, scaling, maintenance, monitoring, and updating is no longer the responsibility of technical teams.

Lambda

A lambda function is a feature of Amazon Web Services that provides a serverless calculation service.

The lambda service is becoming increasingly crucial in AWS services, as evidenced by the number of events to which Lambda can subscribe as we can see below:

HTTP API Gateway

AWS provides its API Gateway. This tool allows you to create an AWS infrastructure entry point and manage HTTP routing, SSL termination, request authentication, and even input and output data conversions.

You will be able to execute your lambda code during an HTTP GET, POST, or PUT call...

The Automated Task With Cloudwatch

You can trigger your Lambda based on a job or cron in the period you specify. Send a newsletter to your users, for example, at the start of each month.

Work with SQS

When you are connected to an SQS queue, you will be able to consume messages from the queue to launch asynchronous tasks.

Lambda Function Scaling

Lambda creates an instance to handle the event when your function is called. When the function code has completed its execution, it is ready to handle another request.

If the function is called again while a request is still being processed, another instance is allocated, which increases the function's concurrency.

Concurrency is limited by a regional limit that applies to all functions in a region. You can use Reserved Concurrency to ensure that a function can consistently achieve a certain concurrency level.

What Is Platform As A Service (PAAS)

Caroline — Mon, 30 May 2022 20:45:18 +0000

PaaS is a cloud computing model that allows developers to build and host applications very quickly without worrying about maintenance, repairs, and more.

It is an independent platform where developers can host software and hardware tools.

PaaS requires no server maintenance.

Advantages of PaaS

Choosing PaaS as a hosting solution for developing applications and tools has many benefits.

Let’s look at a few:

Easy Management and Cost Reduction

PaaS technology does not include server and database management.

A PaaS provider creates and maintains a secure and optimized environment for users to install applications and data sets. Users can concentrate on developing and deploying applications rather than building and maintaining the underlying infrastructure and services.

That is, in the case of application hosting, it is the platform that acts as the host.
Hence, reduced installation and maintenance costs.

Higher Efficiency For Developers

By PaaS saving money on application deployment, it reduces the time required to spend on a project.

Developers can focus only on the project itself when they choose to use this model.

All other aspects (server, database, virtualization, operating system, etc.) are managed by the vendor.

PaaS is a guarantee of peace but also flexibility.

What Are Some Of The Skills One Needs For A Career In Cloud Engineering?

Caroline — Sat, 28 May 2022 20:51:16 +0000

Cloud engineering has become one of the most in demand skills in recent years. More people and companies than ever, are using the cloud to store their data.

Let’s dive into who cloud engineer is.

Who Is A Cloud Engineer?

Cloud Engineer is a professional who takes care of all technical burdens related to Cloud Computing.

This burden may include management, planning, architecture, and oversight of cloud systems, along with knowledge and implementation of best practices for cloud application deployment.

Cloud engineering is a general term that encompasses several different functions, including:

Cloud Architect

A cloud architect designs and creates the environment in the cloud.

Cloud Engineer

Cloud Engineer deals with cloud computing technological features.

Cloud Security Engineer

They are responsible for protecting confidential data that’s sensitive to the organization, giving support, computing and ensure that they can work remotely in an swift way.

Cloud Network Engineer

A cloud network engineer is the IT person that implements and manages cloud network architectures.

The Skills Required For A Job In Cloud Engineering Are:

Cloud computing standards

Basic knowledge of programming
You don't need any coding skills.
Basic knowledge of database
Understand DevOps methods

What Is Cloud Computing?

Caroline — Fri, 27 May 2022 20:25:22 +0000

Cloud computing is performing tasks, storing data or hosting services on another system, as opposed to a personal computer. This my be due to limitations of performance or specific features on your personal device.

With cloud computing, companies use IT resources such as servers, computing power, storage, middleware, or flexible software over the Internet. You hire different IT resources according to your individual cloud provider's needs and pay for them according to consumption.

What Are The Four Types Of Cloud Computing?

Private Cloud

The private cloud makes its services available only to organizations. Unlike the public cloud, it is not accessible to the general public.

The private cloud can be hosted on the company's computers or by a third party and offers a high level of control and security.

Public cloud

The public cloud is a shared resource among many users. The required server infrastructure is located in the external data centers of the cloud provider.

Hybrid clouds

The hybrid cloud runs simple processes in its private cloud and uses the public cloud for complex processes. You can reduce your costs and various complications that can slow down or slow down your business processes.

MultiCloud

Multicloud aims to run applications in multiple clouds. Many cloud providers, such as AWS, Google Cloud and Microsoft Azure, provide their customers with the computing power, cloud storage capabilities and network resources needed for multi-cloud deployments.

What are the three uses of cloud computing?

Infrastructure As A Service

IAAS Hardware is hosted by a cloud service provider provided to customers through their portal. The provider hosts and manages the hardware. You as a customer pays for the use.

Platform As A Service

PaaS providers provide a platform for hosting customer applications. These are software services offered as a platform. The customer runs each business application as a home application on the platform.

Software As A Service

SAAS The provider hosts the software on its infrastructure and delivers it as a service to customers. The provider manages the infrastructure and software or only provides software and uses other IaaS service providers for the hardware. The customer pays for the use of the software.

What Are The Benefits Of Cloud Computing?

It provides data backup in a power outage, emergency or other crisis. You know that your data is protected in a secure place.

Cloud computing enables flexibility and allows information systems to be adapted to the business needs of companies, which are also constantly changing. This gives them an undeniable competitive advantage.

More resources and greater responsiveness allow companies to focus their expertise on increasing productivity and performance.

Cloud computing was supposedly invented in the 1960s by Joseph Carl Robnett Licklider.

What Is AWS CloudFormation?

Caroline — Thu, 26 May 2022 06:20:51 +0000

What is AWS CloudFormation?

AWS CloudFormation is a free Amazon Web Services tool needed to manage the infrastructure for an AWS management software application.

It is the easiest way to manage AWS infrastructure resources by seamlessly helping with simple modeling and easy setup. It is much easier to create a CloudFormation with a design template that can be designed according to the user's preferences.

For example, a template can define an application's needs, such as the Amazon Elastic Compute Cloud (EC2).

The big advantage is that the user does not have to assess the dependence or complexity of the infrastructure services uploaded to the CloudFormation portal with the above application.

Once the template has been designed, tested, and validated, CloudFormation analyzes and considers user-defined resources.

It, therefore, eliminates manual dependence and makes it easier to verify the focus on the main business.

You need to be aware of two important aspects of CloudFormation; that is the template and the stack.

Why Do You Need AWS CloudFormation?

If the number of infrastructure services and products doubles due to demand, then AWS will not be able to do everything at once.

This is why AWS CloudFormation is available.

It is an infrastructure-like code that can create a seamless clone of the server configuration at any time and reduce AWS problems.

With AWS CloudFormation, configuration changes can be dynamic or barrier-free integrated into the existing environment.

Managing multiple AWS resources is challenging and time-consuming.

Without AWS CloudFormation, developers would focus their attention and time on building infrastructure and services and less on application development.

Building any infrastructure product or service is more difficult and demanding. Even deploying an existing environment is also challenging. This is where AWS CloudFormation saves the day.

Benefits of AWS CloudFormation

Scalability

Templates are completely reusable and can be re-created and rebuilt many times without scripting.

Regardless of whether you at first hope to send numerous examples of similar AWS resources, CloudFormation formats are helpful because they guarantee that you can increase your current circumstance rapidly when you are in need.

By keeping CloudFormation layouts close, you will realize that you can add more storage space.

Template is in Code

The template is code only, and the version is easy to maintain and check. This makes it easy to use for developers.

Speed in Deployment

One can model all the resources in a text file and can always be used anywhere. When you make CloudFormation formats to oversee how AWS resources are designed and sent, you can convey different occurrences of similar resources momentarily utilizing only one layout.

AWS CloudFormation is a powerful tool that makes infrastructure automation simple, designed the way you want it, and easy to use.

Many popular companies use AWS CloudFormation to deploy and manage their resources. If you haven't learned it yet, you should start. Plus, its steep learning curve makes learning fun.

How To Get Started With Open Source

Caroline — Wed, 25 May 2022 19:03:43 +0000

What Is OpenSource?

In general, it is a computer software that the developer distributes under a license that allows anyone and for any purpose to use, study, modify, and distribute the software and its source code.

However, this article will not discuss the software.

In this article I am going to look at opensource as a community. How you can contribute to it and mentoring others.

Mentoring and assisting others is an integral part of opensource. You're distributing your ability to others so they can benefit from the knowledge you possess.

To begin, let me state that I have struggled with imposter syndrome and have a constant sense of inadequacy. Additionally, I am a very solitary person. If an introvert had a scale, I would unquestionably be at the top.

However, I discovered some interesting people via tech Twitter. And I've been loitering in their quarters. That is the most significant discovery I have made since I started learning programming languages.

Their words have been instrumental in motivating me to continue. And in this article, I'll share their wisdom from a recent geek out session with you.

Let's begin by dispelling a myth that prevents many newcomers from putting themselves out there and sharing with others.

Who Should Become an OpenSource Contributor?

You should.

As the name implies, it is open. It is open to all.

Open-source communities are conceived with the express purpose of hearing your perspective and soliciting your input. That is a place where no one wishes to exclude you.

The opensource communities exist to facilitate the exchange of novel ideas, conversations, and speakers.

Whether you have one or a million followers, you have knowledge that can benefit someone somewhere, and keeping it to yourself is a disservice to the entire community.

When Is the Best Time to Start Contributing to OpenSource?

There is no perfect moment to begin your contribution.

If you're five days into your journey, you can assist someone who is in the same situation as you were a day ago.

You have something you can give to another person. That single step you took today, someone else will take tomorrow, and they will undoubtedly be grateful to have someone holding their hand.

How To Mentor Another Person

Begin by paying attention to what they are saying.

Listening is critical.

You cannot demonstrate your concern if you are not present.

Keep a side-by-side relationship with your mentee. If someone approaches you for assistance and you say, "Google this, search for this," you're not providing the assistance they seek.

Conduct research and provide a helpful response.

You are not required to do so, but you should if you advertise yourself to be someone who actively assists others.

If you cannot, then make no claim to be an educator or someone who teaches others. Because when individuals approach you in the manner in which you have positioned yourself, they are discouraged and hurt. They believe they are unworthy of your time, which is extremely painful for them.

Believe this. I’ve been there. It is painful.

How Do You Create An Inclusive Space That Is Open To All?

You foster an inclusive environment by assisting and accommodating everyone, regardless of their strengths or weaknesses. It creates an atmosphere of comfort and welcome in the space.

If someone is having difficulty grasping or is not progressing at the same rate as others, take the time to listen to their unique situation and provide them with the time they require.

Don’t forget them behind and continue on with the others.

I speak from personal experience. As a person with a learning disability. I am quite forgetful.

This is critical if you wish to communicate with others.

When people believe that if they approach you with their problems, you will attempt to assist them, they will always feel comfortable speaking with you.

How Do You Become An Opensource Contributor?

By joining communities and interacting with others who share the same interests as you.

Join them all and if you don't like it or it doesn't fit, try another.

Don't join and then lurk on the sidelines. Engage, because being a member of many communities is ineffective if you are not engaging.

Expose yourself to scrutiny. You will not know if you are making progress if there is no one to inform you. And they have no way of knowing unless you show them what you're doing.

And this is coming from someone who is an introvert with additional disadvantages, so I am fully aware of how difficult this is. However, as you can see, I'm exposing myself to criticism here.

If I can do it, then you can as well.

“Anyone who is just coming into the industry or in a junior position please use your voices.” Tanya

If you are a member of a minority group, you might want to look up minority-based communities to get some alternative perspectives and insights, as well as help that is channeled specifically for those groups.

If you're from another country, you could look up local communities to connect with people in your immediate area.

This is not to marginalize yourself, but to establish a network that is close by.

An initiative to expand both internally and externally.

What Is The Advantage Of Helping Others?

Assisting others also helps us learn new things.

Occasionally, mentors do not possess all of the answers. Rather than snobbery or indifference, you can take steps independently to find an answer to that question.

Yes, it may seem like a waste of time to go to the trouble of looking that up for them, but in the end, it is beneficial to you because you are also learning.

Providing assistance to others is not a one-way street.

Why You Should Share Information To The Public

Someone is going to find value out of it. If it resonates with even one person, it is a success.

Always make an effort to assist the person next to you.

Dispense your knowledge about the things you've learned.

Bear in mind that you do not have to change the entire world. You only need to make a difference in the life of one person.

When Should You Begin Mentoring Others?

There is no defined start time. Begin whenever you feel at ease and have something you'd like to contribute back to the community.

Create a blog post about a new skill you've acquired. Document how you built your first project. It will benefit both your juniors and the community.

I am currently self-teaching myself how to program. I usually watch YouTube tutorials on how to do something before attempting to replicate it on my own. Then I practice daily until I am able to do it without referencing anything and by adding my own codes.

Therefore, consider what would happen if those developers had not created those YouTube videos. I'm sure I'd still be saving for college to study Computer Programming!

Therefore, share because it will benefit someone who will be in your position tomorrow.

“Put your knowledge out there on the things you have learnt.” Saumya

How You Can Help Mentor Others

Ask your questions in public

Public forums and the public accounts of your mentors and role models are great places to start helping mentor fellow techies.

The reason you should do this is because there are many more people out there who have the same question as you and they will benefit from you asking in public.

Mentors answer the same questions every day, thus asking in public allows them to respond to a large number of other people who have the same query.

Additionally, asking in public allows you to receive an answer more quickly than sending someone a private message.

Most of your mentors probably have a large following, and receive a large number of direct messages. So it’s easy for them to miss your private messages.

As a result, it may take time for you to receive feedback. Alternatively, your message may get buried in their DMs, and you may never receive the assistance you seek.

As a result, always address your inquiries to their walls. If they do not respond, someone else with knowledge of the situation will.

Provide Responses to Questions You Are Aware of the Solutions

If you see a question and you have an idea of the solution, don’t hesitate to help.

That is how some of the mentors were made.

By answering one question after another, people will see how helpful you are and will follow you since they will know you are willing to help.

You can be a mentor to someone and not realize it. I have people on a private list on Twitter because I don't want their tweets to get lost in my timeline. So every time I open Twitter, I check that list first.

So, ask or answer questions in public. You have no idea who you may be assisting.

The blogs may also prove beneficial as a revision tool for you in the future.

If you're just starting out, sharing will accelerate your learning process because you're not only consuming but also giving.

The Imposter Syndrome: How to Overcome It

If there is one thing that prevents the majority of us, including myself, from contributing to opensource, it is self-doubt.

In our minds, there is a lingering sense of defeat and unworthiness.

I've learned something about imposter syndrome that I'd like to share with you.

It's quite interesting.

Every senior developer you meet who oozes confidence and is free of self-doubt has struggled with it at some point in their career.

Not only when they were first starting out, but also as established professionals in their field.

There’s many new things coming up everyday. Nobody can claim to be an expert on everything related to technology. Technology advances at a gradual pace. What you use today will be superseded by an updated version tomorrow.

Make no apprehensions about putting yourself out there. You are not a fool. What you know, the individual who is beginning does not.

Write about the new knowledge you've gained in a blog, a vlog, or on a podcast, or in any other format you're comfortable with. If just one person reads it, or if it resonates with and supports them, it's a success.

It's a win-win situation for both parties.

If you teach something to someone, it will stick with you more. As a result, your personal development is aided.

Remember contributing to OpenSource is a two way thing. You can support and be supported creating a supportive community.

“Sharing helps us learn new things as well. People feel it’s an investment of time but it’s also investing in us.” Sohini

I'll give an example with myself. This blog is a result of Eddie Jaoude's twitter space on the same topic am writing about.

The time it has taken me to write this blog has allowed the words spoken in that space to sink even deeper into my mind.

I listened in on the day itself. I made no notes. Why? Because I did not want to be distracted. I have ADHD, if I divert my attention to something else, I risk forgetting everything.

Later, while taking notes, I listened to the recording. I listened again just to be sure I have grasped it well, as my brain is notoriously forgetful. I frequently doubt whether I am doing the right thing.

As a result of listening and crafting points, writing them down and explaining them to you in this blog, I have retained them in my mind.

If you can put it in your own words, then you've understood it.

Thus, this is my contribution to the opensource community. I'm not yet a master at coding, but I am documenting my journey for you and me.

Therefore, if it's an article, video, or podcast, publish it. If you look at it years, months, or weeks later and are embarrassed by it, you will know that you have made progress.

You will be able to stand and declare to those just embarking on their journey, "Here is my proof! I began here. I was not flawless from the beginning.”

Nobody begins perfectly.

Thus, this is how you develop and improve.

Please use your voices if you are new to the industry or in a junior position. Do not believe that because I lack x number of years of experience in technology, all I need to do is learn from others. You may also contribute. You have life experiences. Your life experience will always be beneficial in the field of technology.

You were destined to be here. You are not an imposter.

Take the initial step. Once you've taken that initial step, you're part of open-source community.

Maintain a sense of reality

The narrative that coding is simple is complete nonsense. This narrative is the primary reason why so many people fail and give up halfway through programming.

If you keep telling people that coding is simple and that they can learn it in a few days, when they encounter a roadblock, they will conclude that they are not cut out for it.

That is the entire purpose of mentors and role models. You are aware that if they can do it and continue to do so, then you can as well.

Be honest about your journey.

Do not only demonstrate your successes. Tell people about your struggles too.

Naturally, that is the way social media is programmed. To demonstrate the good. However, showing your authentic progress will assist someone starting with developing a sense of comfort with their approach to programming.

It will help those considering a career in coding in developing a positive attitude towards their goals.

Genuineness gives a positive effect.

If you're blatantly clear with them and show them the ups and downs as well as the smooth sailing, they'll stick around when they hit that hard rock. Because they were prepared from the word go to and can face their mountains.

How To Give Effective Feedback

Sandwich your response.

If you're going to give someone criticism, do so in this order.
Make a point of highlighting something truly remarkable about what they accomplished.
Give the criticism and then compliment them on something else they did well.

If you only approach them with a negative attitude, they will go into defensive mode, and you will eventually lose them.

If someone approaches you about a piece of code or a solution, for example. If you begin by praising something they did well, then offer constructive criticism, and conclude by praising something else they did well, you send them positive vibes.

Open Ended Replies

If you receive a question in the same scenario as above, here is another cordial response.

allow them to speak and lay out their rationale for not being able to resolve it.

Provide them with options and allow them to brainstorm using the various ideas you've presented.

Once the brainstorming session is complete, you may ask follow-up questions.

Which concept or solution did they choose?

Why did they choose it or was it the correct decision?

If you notice they're completely off track, you enter and offer some suggestions.

This type of response aides them in resolving their issues.

It's open ended in that they have the opportunity to weigh in on alternative solutions before settling on one, thereby learning new ways to approach the problem.

Do not be married to a single concept.

Have you encountered them?

Those who will not accept that your idea is good to simply demonstrate their superior knowledge.

The funny thing I've discovered about these types of people is that they'll use your idea and sell it as their own days later.

No citing of the original source.

Consider feedback, conduct research, and remain adaptable and receptive to change.

What Are the Requirements to Become a Mentor and Contribute to OpenSource?

Knowledge

You cannot give what you lack. First, educate yourself, then assist.

Patience

Individuals repeatedly ask the same questions. They'll still DM you with the same questions even if you post in public. Be patient. It is a virtue that will enable you to be in harmony with the community.

Conclusion

What, then, can we learn from these technology gurus?

Supporting the success of another developer will never, ever jeopardize your own."

By showing your concern, you are uplifting developers of all skill levels. This in return has a profound effect on the entire community.

If you have a problem, someone else does as well. Individuals are fearful of being perceived as fools. It is a necessary step in the process. The genius you see in technology is a buffoon in another field.

It is perfectly acceptable for a beginner to seek external advice or assistance. While sharing your goals and dreams is acceptable, do not allow someone else's opinion to derail your momentum or progress.

It is acceptable to admire and look up to others as role models. Simply avoid using it as an excuse to lose your focus and forget your skills. You're doing well right now. This is not a race, nor is it a sprint. This is technology. It is a case of one code at a time.

Do not be afraid of failure. Failure teaches you something about yourself. Will create a more perfect version of you. Provide you with a new position in which to gain experience.

It takes genuine courage to continue forward.

It's exciting at first, but after a while, it becomes routine. Both inspiration and motivation have a shelf life. After the excitement subsides, your commitment takes over.

Don’t allow the initial excitement to propel you into a pace that you cannot sustain. Attempting to compete in order to complete within a specified time frame.

Burnout happens to everyone. Try to avoid it by resting both your mind and body.

Your mental health matters.

I’d like to say thank you to the panel that made the twitter space that made this blog possible. Eddie Jaoude, Danny, Sohini, Goobric, Saumya, & Tanya.
