The development world is increasingly embracing microservices as it makes the development process easier and quicker. Developers use microservices to build more substantial and more complex applications that are developed and managed as a combination of small services. These small services work together to provide the application a broad, extensive functionality.

Microservices are also referred to as “piece-by-piece” development methodology. Let’s dive into Java microservices, and how it can be deployed with AWS.

Microservices: An Overview

A microservice is an architectural style that develops an application as a combination of several sets of small services. Each service operates independently and runs its own process. These services communicate with each other and with clients using “messaging over HTTP” and other lightweight protocols.

In simple words, microservices can be considered as a type of service-oriented architecture applications developed as a collection of several smaller services, instead of an entire app as a whole.

Thus, in microservices, instead of having a monolithic application, you have various independent apps that function separately on their own. You can create these sub-applications using different programming languages, even different platforms.

By utilizing the microservices methodology, you can structure big, complicated applications to less complex mini-programs that run independently. These small programs are conglomerated to deliver the comprehensive functionality of a big, monolithic application.

In microservice developments, the need for a large team working on a massive monolithic project is eliminated. In the case of microservices development, small, agile teams work individually to develop the programs they are most comfortable working with.

All the programs developed are independently executed, scaled, and versioned. These services are programmed to interact with other microservices. They have unique names and URLs and are consistently available in case of failures.

Benefits of Microservices

Microservices offer a wide range of benefits, ranging from helping developers with coding to influencing the architecture. Here is how microservices can help you with application development.

Easy Development and Maintenance of Applications

The major advantage of microservices is its simplicity. Applications, when split into smaller, more composable fragments, become easier to build and maintain. Microservices also eases the process of managing codes by providing a separate chunk of codes, which otherwise would have been a tedious task to do.

Microservices also support the implementation of services using different programming languages, software environments, and databases. This flexibility enables you to deploy, rebuild, re-deploy, and manage each service independently.

For example, if a service allows too much memory or puts a significant load on the process, no other services will be affected, but the service responsible for the load itself.

Therefore, any problem occurring in one microservice will not affect the entire system, making it easy to compensate for the failure of a particular service.

Business-Oriented Orientation

Microservices help you build products, instead of projects. Microservice architectures enable teams to focus on prioritizing business functionality instead of sticking to writing glue code. Business teams need to stay organized around business capabilities, instead of technologies.

Programs developed using the microservice architecture are adaptable, and can be used in multiple contexts. Therefore, the same service can be reused in more than one business operation or business channel, depending upon the requirement. Microservice methodology also ensures each team member is responsible for a specific service, which promotes the development of smart, agile, and cross-functional teams.

Improved Speed and Productivity

The microservices architecture also enables you to counter the challenges of speed and productivity by disintegrating applications into smaller, manageable services that are faster and easier to develop. Different teams can work on different elements of a project without waiting for a team to finish its share of work. This architecture also comes in handy for fastening quality assurance as every microservice can be individually tested. Therefore, you can test the components which are already developed, and the programmers can work on developing other programs.

Flexible Technology and Easy Scalability

As mentioned earlier, each microservice can be written utilizing varied technology. This flexibility simplifies the process of selecting the most appropriate tech stack for a particular need of a service. The microservice architecture also enables decoupled services written in variable programming languages to coexist with other components.

It can also be helpful if you are looking to scale your product. Microservices allow you to seamlessly add new elements to the system, along with providing the ability to scale services individually from one another.

Cross-Functional, Autonomous Teams

If different teams working on a project are inefficient, microservices can be a blessing. Developing a huge monolith program can be a messy and complicated task, especially if you are working with divisions with extended teams around the globe.

Microservices provide developers with more independence for working autonomously, which helps in speeding up the process of decision making in smaller groups. Therefore, if the solution you are planning to develop is huge, consider utilizing the microservice architecture.

Java Microservices Frameworks

If you are developing using Java, you can use a plethora of microservices frameworks. However, the best ones include:

Spring Boot: Spring Boot is the best and most widely-used Java microservices framework. It works on top of languages for Aspect-Oriented Programming, Inversion of Control, and others.

Jersey: Another popular Java microservices framework, Jersey, is an open-source framework that supports JAX-RS APIs in Java. This framework is one of the easiest to use.

Swagger: Swagger is a microservices framework for Java that helps you with documenting API, along with providing you a development portal that enables you to test your APIs.

Apart from these, some other popular frameworks you can consider using are Dropwizard, Play Framework, Ninja Web Framework, Restlet, RestExpress, & Spark Framework.

How to Deploy Java Microservices to AWS?

If you are curious about how you can deploy Java microservices on Amazon Web Services (AWS), this piece of information can help. Check out the best recommendations for using Java microservices on AWS.

AWS Fargate (Amazon Elastic Container Service or Amazon ECS)

Since microservices don’t translate into containers, you can deploy a monolith application with microservices utilizing physical host or virtual machines. However, it is essential to acknowledge the working of containers and what they aim to do. You can deploy services as a set of containers that can commute with one another.

Amazon ECS helps you define your cluster, along with analyzing metrics to configure scalability. If you want to skip the hassle of provisioning, such as managing the cluster, type of instances, and deciding when to scale, you can rely on AWS Fargate. Not only will it take care of the provisioning for you, but it will also integrate with other services like IAM, AWS Elastic Container Registry, and Amazon CloudWatch.

Amazon EKS (Amazon Elastic Container Service for Kubernetes)

Amazon EKS is the “Kubernetes as a service” alternative on AWS and can come in handy if Amazon ECS cannot cover your requirements. If your deployment structure needs the Kubernetes engine, don’t worry as you are covered. Amazon EKS enables you to run containers representing microservices, along with grouping them via services and pods.

Amazon EKS also offers integration with several AWS services, including IAM, AWS App Mesh, etc.

AWS Lambda

If your business frowns upon you having your application running all the time, you can characterize your application as a set of serverless functions. Therefore, you can group them to display as an independent service.

AWS Lambda enables you to deploy functions that can run on demand when an event takes place. If you attach the functions to HTTP calls, you can develop an exceptional API that can cover your company objectives. One of the significant benefits of Lambda is that AWS charges for execution time only. AWS Lambda also supports seamless integration with AWS API Gateway, which helps you monitor and secure your API as per requirements.

Best Practices for Microservices

By now, you must have realized that shifting to microservices can be a major advantage for your business and development operations. They provide opportunities for greater reliability, increased scalability, and reduced costs.

However, you can encounter some challenges while using microservices as well; therefore, it is essential to follow some practices for seamless migration.

• All of your microservices should use their data store.
• The development and DevOps teams choose the database for all their services.
• When teams share a database, the chances of creating a monolithic service increases; thus, it is essential to be cautious and alert.

Wrapping It Up

Microservices have revolutionized the app development process and has helped distribute the cumbersome process of creating a monolithic program into small, individual mini-programs that can be programmed using different technologies, and that too on different platforms.

It also offers seamless scalability, which makes it an excellent choice for deploying in AWS. The best Java microservices frameworks include Spring Boot, Jersey, and Swagger. For deploying microservices in Java, you can use AWS Fargate, Amazon EKS, or Amazon Lambda as per your requirements.

For software architects, microservices are the wave of the future. Sounds convincing? To learn more about the advantages of microservices architecture, check out the top 10 reasons.

Also, make sure that you know about all the barriers in terms of technical complexity, stack, and more moving to the microservices architecture.

Java is a language that has been around for some time, and people wonder if it is useful in a microservices setting. This article explains the advantages of microservices architecture and why Java still has a lot of significance in contemporary apps such as microservices.

The Need for writing the microservice applications in Java

For excellent reasons, Java is a common linguistic option. The language is strong, with years of experience working with critical apps for missions and evolving with the emergence of fresh planning models. The near-omnipresent use of Java in company apps has developed an extensive pool of Java-based software developers. Even when fresh apps are created, it is useful to use current abilities.

The intensive learning curves are provided by microservices with the addition of a language to the mix which may increase the danger. It presents yet more unidentified information about the creation, deployment, and administration of a manufacturing microservice implementation.

To revolutionize your organization, it’s always positive to keep an eye on the upcoming technologies, frameworks, languages. If in your monolithic framework you are still cemented in your cube messing around with code, then you probably live in the past, where you have a small application and some employees to handle it.

JavaScript is usually used for the application front end (particularly for web-based applications). Java for battle-tested data management is also common in the background. While there is still a lot of space for spectral variations, Java is great for writing micro-services.

Nowadays, things have been changing. You have to go a step forward and walk with the revolutionary technologies where microservices are among the leaders. Are you looking for the best reasons to invest time in learning microservices with a view to becoming an architect and developing applications using them?

This article will help you in learning various advantages of microservices architecture and various reasons so as to why learn microservices.

• Various Tools can be used flexibly as and when required

The architecture of microservices encourages the use of the most suitable technology for the service’s specific needs. Each service is free to use its own language, framework or auxiliary services. The services still communicate easily with the other services in the application even with the use of such diverse frameworks.

• High-Quality code is provided

The entire framework is modularized into discrete components following the microservices architecture. This helps the application development team concentrate on one specific job at a time. In turn, this simplifies the overall process of coding and testing.

• Various Applications can be easily Built and Maintained

The team of developers divides into the following activities as and when the products built by developers become stable and are available for customers.

• Implementing various new features
• Bug fixing
• Modifications in the existing features

If the product is based on a monolithic framework, each change to the codebase must pass through all stages of construction, maintenance, and deployment. Microservices are a savior in these situations!

• The Technology Stack

The technology stack is difficult enough to decide for a monolithic application, but for every microservice, this decision must now be taken. What seems theoretically attractive can become difficult in practice if your services are too heterogeneous. Standardization is becoming a problem and cowboy behavior is possible. It’s also more difficult when every team has a totally different stack for people to move between teams.

It is always recommended to have a balanced approach where the application has a preferred technology stack. If any team wishes to override this default stack, it should justify the fact that it is better suited for microservice with advantages and disadvantages. Your stack of technologies should include the language of programming, test, and logging, cloud providers, facilities, storage, monitoring, etc.

• Improvements in the Scalability

The main aspect of microservices is scalability. Since each service is a separate part, a single function or service can be expanded without the application being scale-up in full. Business services for increased availability and performance on multiple servers can be used without affecting the efficiency of other services.

• Faster Market Time

Due to the fact queuing up of microservices, you don’t need to rewrite all the codebase for a feature to be included or modified. Only a specific service will be changed. You can quickly market your application and services by the development of applications in smaller increments that can be independently tested and deployed.

• The Complex Operations

The complexity of operations is much increased by microservices as operations must be revised from a fundamental point of view. The following aspects must be considered:

Infrastructure

The definition of microservice infrastructure requirements and subsequently the provision and maintenance of infra for each microservice creates a level of complexity which most monolithic Ops engineers are not used to. Furthermore, as these services are expanded and reduced, the infrastructure must be automatically provided and reduced, thus requiring a very advanced level of automation.

Load balancing and scaling

It is likely you will need a much more complex, scaling strategy than with monolithic, ever-scale(x-axis) applications. If you need to scale all the services or just a subset when there’s a high demand, you’ll need to figure out with Microservices. The y-axis scaling is essential for the operations team, as the microservices approach and z-Axis scaling are consistent to obtain x and y.

Service detection

Dynamically, due to scaling and upgrades, the set of service instances of a world with microservices. Services also have dynamic network locations, so you need a way to discover new services. For this, it is always recommended to go for a registry service such as Consul because it works very well.

Monitoring

This must be configured and maintained on every microservice to make the operations team engineers more complex. In addition, the surveillance solution must manage situations for increasing and downloading a subset of facilities.

• Delivery is Continuous

In contrast to monolithic apps where devoted teams operate for each individual function like database manipulation, server logic retention, microservices utilizes the continuous delivery model to manage the entire application lifecycle.

The developers, the test teams and the operations team work together on the construction, testing and debugging of a single service.

• Risk Reducer

Every service in the microservices framework is a distinct entity, which enables localization, increased confidence in quality, and end-to-end regression scenarios. Even if one service or application element is down, the entire application will not decrease. Rather, the designers only need to rebuild that specific service or element. This decreases the danger of your company application being completely dropped!!

• Delivery is Continuous

In contrast to monolithic applications in which dedicated teams are working on discreet functions such as UI, database, server logic and technology, microservices employ cross-functional teams to operate on a continuous delivery model for the entire life cycle of an application. Testing and deployment become simple and instantaneous when developers, activities and test teams operate on one service concurrently. Code is constantly being created, tested and implemented through this strategy of incremental development, and instead of reinventing the wheel; you can use code from current libraries.

Cloud Technology is Soaring High & with Microservices, it’s Taking the Center Stage

The recent years have seen a lot of changes happening in the tech world. Groundbreaking innovations and fast up gradation has become the name of the game now. This is the Century of technological evolution and there is no denying that.

The advancement of technology has pushed developers and organizations to accept and implement new ways over traditional methods. It’s the only means one can compete and thrive in this digital era. If you look back at the year that went by, 2018 was remarkable for developers all around the world. Things became smarter and easier with increased usage of cloud computing. There were some great work done in the field of microservices and a fair share of attention and importance was given to serverless architecture.  

With all these technological revolutions happening, the techies are already predicting an equally productive and innovative 2019. Many developers in the field are having this idea that, with increasing implementation of microservices, it can very well become the future of development in the broader aspect. So let’s shed some light on the subject.

Let’s Understand Microservices better

Microservices can be referred to as the architecture involved in the development of software and applications both web and mobile based. Now, there are monolithic architecture and the traditional SOA that have been in use for long.

The thing with monolithic is that all the changes in software or application need to be made all at once. It’s either all or nothing. In the SOA, one can alter one piece at a time. However, it has to be done in a way so that it can fit into the original structure after the changes are made without any difficulty.  

Microservices is better than both as it gives you the liberty to build, maintain and update anything separately. After everything is done all they got to do is connect the update with the help of a shared data API. It basically allows you to work on independent pieces without causing any alteration to the overall structure.  

For example, microservices allow you to make individual changes to separate functions like social media logins, search engine, user management, e-commerce cart, etc. You can create and update it in a different programming language using diverse data storages. There is no concept of centralized management. They use HTTP, Thrift APIs, REST, etc. for communicating which is light and easy. Microservices offer you a platform that focuses on independent deployment and flexibility. It’s the model child of this modular driven world.

Past Advancements In Microservices

Before we take a peek at what the future holds for microservices, let’s do a flashback on the subject. More and more developers are implementing microservices in creation and maintenance of software and apps, to boost their flexibility. The wide usage of cloud services has made the transition to new ways even easier. One can say that both technologies are interdependent. Microservices allow the developer to produce fast and effective solutions all the while maintaining high-quality performance.  

One can rightfully say that it is hard to keep up the pace with today’s fast updates trend with the old monolithic structures. It is time-consuming and makes the work that much harder for the developer. Though there are conflicting ideas in the developer circle, things do look brighter on the microservices side.

Go Serverless

No technological innovation can work alone without support from reliable and equally advanced services. Same goes for microservices. Serverless architecture has come as a boon to developers who wanted to work using microservices. It is an appropriate foundation that can well support the agility of microservices, one that the traditional servers could not. Container structures have a higher overhead and rigid approach which is not a match for microservices.

Hence developers switched to a serverless architecture. It is as flexible as microservices itself. There is absolutely no need to invest in unnecessary server resources. With cloud service providers, one has to pay for just the specific resources that they require. Many event databases have already gone serverless and more are queuing up. So basically microservices and serverless structure have both helped each other in their quest of technological development. According to developers, the camaraderie is to only grow stronger in the years to come.

Microservices In The Multi-Cloud Future

Cloud technology is soaring high, and with microservices taking the center stage, it will be a sight to see how well it performs across a multi-cloud environment. According to developers, multiple cloud approach can be very beneficial to the microservices solutions. It allows you to broaden your spectrum instead of staying confined in allocated server resources.

Multi-cloud services give you access to a number of features that you can utilize as per your development and maintenance requirement. It even allows you to run complex apps, unlike allocated server resources.

If you are using microservices that are closely related to information management and database, then you can use Oracle’s cloud services. For added storage and archives you can refer to Amazon S3 and get the benefits of AI integration and analytics by using Azure. That’s how you reap the benefits of microservices in a multi-cloud environment.

Getting Ahead Of Kubernetes

Kubernetes helps a lot to handle or rather in the proper management of containers and cloud computing. When it comes to the adaptability of containers, Kubernetes can make the process quite easy. But one should not forget that there is still the question of it carrying overheads for containers, which leads us to the question of serverless architecture.

In 2019, one can get to see serverless architecture gaining more prominence in the tech world. Most of the web development projects today focus on controlling the costs. And when it comes to cost-effectiveness nothing can beat the serverless architecture. It makes it very easy to handle spikes and use specific resources that you need. It gives you the boon of full functionality at low operational costs.

You can even improvise it by using the right combinations, such as Cloud Firestore and S3 to manage and support multiple cloud serverless structure. You can even run transactional tasks across a multi-cloud environment by integrating cross-server encryption. It might be complicated but quite easy if you implement the right techniques of cloud technology and serverless architecture.

CONCLUSION

All these advancements and integration take us to one final thing and that is client management. Normally the client interface is used on the presentation layer. But when you are building apps with microservices across multiple cloud environments, it can be modified for diverse clients.

There are a lot of changes in the tech scenario and advancements to look forward to this year. What the past year has proved is that microservices along with cloud technology and serverless architecture has already made its mark in the technological arena. Let’s wait & watch, what advancements it leads to in 2019.
