Microservice architectures have become quite the buzzword in recent years. Many believe they are the future of web applications, and why most large tech companies use them as their main platform for software development.

A microservice is typically defined as an autonomous service that can work independently from other services. This allows each individual service to focus on one specific task, which cuts down on overhead that might slow down its performance when working together.

There are several benefits of using microservices over traditional monolithic apps. Some of these include faster deployment times, easier maintenance, and better scalability. All of these qualities help boost a company’s image and keep users coming back!

However, like anything new, there are some drawbacks. One major drawback is how difficult it can be to coordinate tasks between different teams. In a monolith app, everything is easily accessible, but this isn't the case with microservices.

Luckily, there are certain strategies you can implement to minimize communication costs. By understanding the basics of microservices, you will know what steps need to be taken to reduce overhead while keeping your projects moving forward.

Benefits of microservices

One significant benefit of microservice architecture is that it allows for rapid development cycles. By separating out components, you can develop and update each component independently.

This gives developers more freedom and flexibility in how they approach project requirements. Since individual components are independent, it also opens up new possibilities for reusability.

By incorporating software design patterns such as event-driven architectures and use cases, it becomes easy to build upon or extend an existing component. This cuts down on overhead related to integrating and extending pre-existing code.

Because microservices are built using open source technology, there are many different options available. This helps reduce costs and increases overall sustainability. It also encourages innovation as people can contribute back to the community.

Lastly, due to their small scale, microservices are much easier to deploy and manage than one large service. As such, this framework is ideal for developing and running projects with limited resources.

Ways to start a microservices project

Starting a new software projects that are built on a microservice architecture can be quite daunting at times. There are many things you need to consider before diving in, and it is easy to get lost along the way!

There are several ways to begin your journey towards building microservices. Some of the most common strategies include starting with one small service first, using an open source tool or framework as a template, or creating a cluster of services yourself.

This article will talk about some of these strategies and what makes them good for beginners. We will also look at how to choose which strategy is best for you and your team depending on the size of the project and time frame.

Create a microservices project

Creating a new microservice project is easy, there are several good tools that can help you do it quickly. You can use an online tool or software package such as Google Suite (Gmail, Docs, etc.), Microsoft Office 365, Slack, Discord, YouTube, Facebook, and others to create your service easily.

Most people start with GitHub because it is free and very accessible at first. Once your service starts getting more complicated, then you can move onto paid services like GitLab or BitBucket.

There are many ways to organize how each individual microservice in your system works. Some people prefer using Ruby for their code, some Python, some Javascript, and so forth. There are no wrong choices here! It totally depends on the type of person what language they feel most comfortable with.

Once your microservice project has been organized into separate apps, it’s time to pick a technology to develop them all on.

Choose your platform

Now that you have determined that microservice architecture is what you want, you will need to choose which platform makes the most sense for your business and team. There are many different software platforms that can be used as a starting place for creating separate services.

The key thing to remember about choosing a platform is to pick one that allows you to quickly develop and deploy individual services while using tools that are familiar to your development team.

A common platform in this case is something like Node or Python-based technology such as Django, Flask, or Pyramid. These all offer similar interfaces and tooling to make developing apps easy. Dependency management is also easier with these types of languages due to modules that can be installed through an automated process.

By investing in the infrastructure side early, it becomes much simpler to implement microservices later.

Design your microservices

At this stage, you will have some small services that do one specific task. It is important to understand that not every service needs to be an app!

Services such as Amazon or Google are very successful because of how they organize their resources. For example, Google has many different services that work together to provide users with fast access to information.

These types of systems are referred to as SOA (service-oriented architecture). A system like this comes together sequentially through links in a network which can be repeated and organized into other networks. This concept was first described in 1972 by Vinton Cerf and Robert Taylor as “the internet”.

Today we call these linked groups of computers and servers software applications or, more commonly, apps. Systems like this are what most people refer to when they talk about technology being built up layer upon layer until it is hard to see where all the components come from.

However, there is a deeper level of organization within apps than just layers. These lower levels of organization are called architectures.

Architectures break down apps into parts that work separately but also connect to each other so that they can pass messages and data back and forth. An example of this would be email programs like Microsoft Outlook or Gmail, both of which have separate windows for sending and receiving emails, folders to store messages, and desktop clients to access them.

Build your microservices

Now that you have determined that microservices are necessary, it is time to start building them! The first step in this process is to pick an appropriate technology for each service.

There are many options here – some of which may seem contradictory at first. For example, choosing Node.js as one service platform might seem crazy since it is already part of the equation.

However, keeping things simple makes deploying new services much easier. Also, being familiar with JavaScript will help you quickly get up and running with most open source microservice frameworks.

Another important factor when picking a framework is how well it supports test-driven development (TDD). This way, not only can you develop functionality rapidly, but you also ensure that everything works properly before deployment.

You should consider both price and availability of professional support when looking into these tools. Some free resources such as GitHub and YouTube can be very helpful in this case.

Test your microservices

A large corporation with over one billion dollars in revenue will likely have many different departments that are involved in creating and promoting new products. With all of these moving parts, there is always someone else doing their best to keep the company afloat!

As we've discussed before, too much focus can be placed on producing an app instead of ensuring that the internal processes remain solid. By having separate groups tackle individual tasks, it becomes easy to remove or shift responsibilities without too much worry.

This concept was first coined as "theory of separation" back in 1982 when software architect Ron Jeffries wrote his paper about it. Since then, it has become increasingly popular due to its effectiveness in developing trust among coworkers and giving individuals responsibility for specific projects.

Deploy your microservices

Now that you have picked an architecture style, it is time to move onto the next step which is deploying your individual services or micro-apps as separate apps!

This article will go over some steps for doing this in both AWS and Google Cloud Platform (GCP). It also goes into detail about how to deploy using Jenkins and what each tool can do for you.

We will be assuming that you already have access to either of these cloud platforms and are familiar with at least one of them. If not, feel free to skip parts of this article until you are!

AWS

Deploying applications on Amazon Web Services (AWS) takes slightly more work than their competitor platform, but they offer tools and features that make it much easier to manage large amounts of data and resources.

A key difference between the two companies’ software deployment strategies is who owns the infrastructure used to run the service. With GCP, you pay per usage whereas with AWS, you are paying per instance all the time. This makes sense considering most people use their web browser several times a day on an always-on device so why should you be charged for that?

With AWS, if you ever want to take down a service, you would need to first delete its instances before deleting the account. The same goes for if someone wanted to add another person’s account as a user. They would need to create new users for the service before giving it to them.
