Migration Approach

In order to migrate to microservices, you must first make a decision on a microservices architecture. Before trying to optimize its implementation, it is necessary to evaluate how the services will interact. Next, continually optimize those speed gains that microservices architecture provides. This requires flexibility in the tools used in deploying the architecture.

To migrate to microservices, a practical three-step approach is suitable:

Componentize: From your already existing applications, select a component and create a microservices implementation on a pilot basis.

Collaborate:  All stakeholders, programmers, and developers on the team should know about the techniques and lessons learned from the Pilot in Stage One. This keeps them updated with new processes and initiatives.

Connect: Complete the application and connect to users in a real-world scenario.



Microservices Benefits

Microservices Architecture comes with a lot of benefits. Some of which include:

Agility: Banking and Fintech applications are designed to be complex, constantly evolving and scaling, integrating with multiple systems (internal/external) as well as demand high security at various levels. Microservices support greater agility in building and managing these systems making them highly suitable.

Scalability:  Unlike a monolithic application that has a lot of resources wasted for scaling services that are not required since they are all packed together in a single deployable unit, each microservices can scale independently without affecting the other microservices.

Availability: Failure of one microservices does not affect other microservices, as the failed one can be uninstalled and rectified quickly with minimal downtime. It does not require the entire application to be brought down for maintenance, unlike the monolith application.

Maintenance: A separate microservices is created for each business service. This means that the amount of codebase is reduced and functional changes can be faster and more efficient due to the decomposed architecture.

Separation of Business Concerns: Microservices offer a clear separation of business concerns as each Microservices caters to particular business functionality.

Faster Deployment: by catering to single business functionality, the code-based required for microservices are reduced, creating a rapid deployment.

Wrapping Up

This plan for migrating existing applications to microservices is intended to enable organizations to realize the benefits of microservices architectures, such as resilience, scalability, improved time to market, and easier maintenance, with maximum efficiency and minimal disruption to existing applications and services.

The Future of Microservices in 2020

Microservices Trends that will become prominent and pervasive in 2020 include cloud adoption, frameworks, and the critical need for observability. Developers can expect frameworks to evolve for web services to make them faster, lighter, and easier to develop.

1. High microservice market growth

Research and Markets forecast the global cloud microservices market will grow at a rate of 22.5 percent, with the U.S. market projected to maintain a growth rate of 27.4 percent. Companies recognize that the benefits of the microservice architecture and adoption of hybrid cloud across various end-user industries are major factors influencing growth in the microservice market.

Microservices allows a development team to implement a new feature or make changes without having to rewrite a large portion of the existing codebase. As for scalability, the independence of microservices makes it easier for an app to grow and change with increased demand.

2. Cloud adoption

Developers will increasingly move away from locally hosted applications and shift into the cloud. Cloud vendors are following this microservices trend, offering all the tooling to build cloud applications natively. Microsoft can even directly integrate tooling with its own programming languages. Cloud adoption will allow companies to implement working service buses that actually manage the functionality.

Many organizations are transforming from a traditional to a digital model of business and are using a hybrid cloud — a combination of a public cloud provider with a private cloud. In addition, enterprises will use big data analytics to gain better business insights and consider hybrid cloud services to make significant cost savings operations.

3. Observability Tools

An important and relevant factor that will affect the future of microservices is observability when the application is designed to expose information about its performance and availability. Observability tools allow app support to track all system calls and service interactions in the case of a failure, to determine where things went wrong. Application teams need to get that data to solve problems. Most companies recognize how important observability is for distributed, microservices-based architectures.

IT organizations will benefit from microservices if they determine the best way to implement observability to support their business needs. Developers should identify the right strategy to implement observability tools without creating performance problems. IT organizations will get ahead with microservices if they figure out how to best implement observability.

4. Frameworks for web services

In 2020, developers can expect the best microservices testing framework to evolve for web services as microservices will make them faster, lighter, and easier to develop. Software developers will be able to use a framework for web services as microservices continue to evolve and offer development out-of-the-box capabilities and implementation of the service design patterns and code automatically.

5. Increased demand to update applications

In response to user demands for interactive, rich, and dynamic experiences on various platforms, many organizations need to update their applications frequently, sometimes several times a day. Microservices can support frequency demand. Plus, microservers provide scalability and agility to the applications having high availability, scalability, and easy-to-execute on the cloud platforms.

A Charter Global client converted its monolithic applications to a microservices design that used open source products for cost efficiency. The client experienced several benefits of the new microservices design:

Upgrading Monolithic Applications into Microservices

Monolithic architecture is typically code-based formed as a singular expansive system. On the other hand, a microservices architecture is formed from a variety of smaller services that each host their own coding foundation. There are a lot of reasons why a company would start with a monolithic application. Monolithic structures can be less work for smaller teams, typically is less complex, and can sometimes process faster than microservice applications. However, monolithic apps can get increasingly difficult to manage and can be very tricky to understand with its many dependent intricacies.


Microservices utilize a batch of services that run independently of each other. For some companies, utilizing this type of architecture is the way to go. Microservices can be much more organized than monolithic apps, easier to manipulate when trying to single out one service, can have easier scaling abilities, and less room for error when changing or modifying an area of code within the application.


The downside that companies run into with microservices is that they tend to require more time to design at the beginning (and with much more overhead). Although, down the road, it can be much more cost-effective changing services in a microservices architecture rather than a monolithic.


For businesses that want to see a faster pace and more adaptability, migrating from a monolithic architecture to a microservices architecture might just be the way to go. Using a team experienced with this form of architecture is crucial for the success of the application. When upgrading, it’s important to build out the infrastructure and management system first, and then slowly migrate over services that are either fairly simple or relatively independent compared to others. Start from edge services and slowly work your way into the core capabilities of the application. It’s important to do it this way so that the core functionality of the application is not affected. If at any point there are services that rely on the monolith core after breaking it away, it’s a sign that this particular service is not defined enough and needs to be reworked into smaller, separate services.


While this might be a rather extensive migration process at first, it will create much more flexibility and scalability in the long run for the application. Charter Global can upgrade your existing big application into multiple independent manageable microservice applications so that each application can run on its own. With microservices, your application will be able to save you measurable costs than if you had stayed with the slow-moving monolithic architecture that once applied to your business but is no longer viable.

Explore the highlights of 5 microservices trends to look out for in the near future.

1. No More Worries about Protocols

Burdensome uncertainty in protocol marked a popular trend in the realm of microservices architecture. Should it be the regular HTTP? Why not the recently matured HTTP/2? Indeed, deciding the best protocol has become worrisome and tedious. However, new developments in protocol will likely eliminate this worrisome task. Why, you ask? There will be the rise of protocol agnostic platforms. So then, users are enabled to communicate with other protocols without intense translation middleware methodology. Additionally, it would in turn aid better connectivity of microservices services. Finally, there will be more robust protocol combinations such as GRPC ->HTTP, HTTP->GRPC, and GraphQL->GRPC.

2. Not Just Functions but Features as a Service

Currently, there are numerous available APIs. It becomes easy to kick start functionality with the aid of helpers such as Firebase and services on AWS. When Microservices Architecture are programmed in a key-based direction, they can act as a feature geared towards multiple applications. A typical example is the authentication of every API, called using an app id. This helps individuals to design really fascinating feature pools and make room for their easy cloud orchestration in an agnostic manner.

3. Container Driven CI/CD

Argo, as well as other projects, tends to treat containers like tasks. Even the version 1.6 of Kubernetes initially introduced containerizes as post tasks geared towards extra configuration. In 2019, adopting containerization to abstract CI and CD will be a major trend. It would be better to treat them as cron job, rather than hook them up in an infra. Also, they should be treated as occurrences resulting from an event firing via code, rather than getting them hooked up in an infra.

4. Microservices Shared Data/Contexts

When it comes to the pattern of building microservices architecture, processes are becoming increasingly ‘loosely coupled’ as well as stern. There’s an emergence of several event-driven tools; typical examples include ‘Serverless’ Event Gateway. This pitches event-driven microservices.

Automated microservices can be enabled via listening to a hitch-free login event of a different microservice inside an application, without manually firing even one event. At the same time, it possesses the ability to control what gets to third party listeners. It’s time to treat today’s microservices with dependencies alongside communication.

5. Less or Zero Worry about Infra

Don’t worry anymore about infra, but focus on their application requirements. The Serverless style will become a focus this year, to enable easy environments to switch away from “always on”. Besides, there’s a need to support additional languages. There should be a possibility for using any language and making it serverless.
