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.

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.

Top 3 Trends In Microservices | Charter Global

Microservices is a software development methodology, or Service Oriented Architecture (SOA) style responsible for application structuring. From the performance of microservices leading up to 2019, experts have identified some trends that will characterize microservices in 2020.

 

1: Test Automation

 

Conventionally, individuals structured test cases for determining whether or not software will work correctly across a wide range of circumstances. QA Automation Testing Services engineers were often responsible for creating and running test cases. The current trend is for software engineers to be in charge of testing, instead of the traditional QA team. This is the result of test-driven development that requires developers to carry out tests throughout the Continuous Integration (CI) pipeline.

 

Businesses and organizations look forward to a software testing services that automates design and has the ability to run and report the results. So, there should be no friction with this solution. It should smoothly connect to CI systems, add comments as a human engineer would do, and analyze new code in real time

 

2: Incident Response

 

The rise of Site Reliability Engineers is a response to the intricately distributed systems. These systems suffer resiliency challenges often. So, the engineers automate manual processes that were previously performed by system admins. Now, they are in charge of efficiency, performance, latency, availability, capacity planning, and emergency response.

 

The financial implications of downtime can be quite significant, which necessitates a fast solution. According to Gartner, this financial implication is up to approximately 6k average revenue loss per minute. In fact, big retail sites, such as Amazon, may encounter up to $220k revenue loss per minute. Overall, it is not just money that is lost, the brand’s image is also at risk with such downtime issues.

 

Solutions are expected to be geared towards providing innovative incident response. Therefore, any centralized platform should also list out the impact and status of the incident, including the event timeline, status and effect on the long run, in addition to assigning roles and kicking off workflows.

 

3: CD/Verification for Enhanced Productivity

 

CD simply stands for Continuous Deployment. There’s always pressure on businesses to speed up software release cycles. With CD, any code that passes testing is applied to production in an automated manner. Compared to CI, the task of ensuring code can be safely and rapidly deployed to production is accomplished by a set of design. Continuous Deployment goes further to manage the full deployment.

 

The manual activities of DevOps engineers are being replaced by CD. Because of this, CD will be aided to become a point of intelligent control for multi-cloud environments. It will make predictive abilities available. Such predictive capabilities include insights into the best region, cloud, as well as configuration for service deployment in line with its circumstances.

 

Finally, experts have predicted that more developers will be tooling around the deployments of microservices, which would cut down the cost associated with complexity. So, organizations can keep on the trend of migration to microservice architectures.

Accelerate Your Application Delivery with QA Automated Testing - Charter Global

2019 will be remembered as an important year for software testing services – with a record 97% of Agile adoption according to Forrester. Upon entering 2020, it’s time to identify several new software testing trends in hopes of achieving new, strategic heights.

As advancements in testing approaches and techniques continue to surge, QA Automation Testing Services teams strive to improve their skill sets. This is crucial in maintaining synchronicity with rapid technological advances that effectively make of break software delivery strategy.

What trends have shown promise in 2019?

Creating a unique, refined, and savory customer experience has taken center stage in 2019 software delivery trends. Growing organizations rely on high-quality software to systematically produce succinct deliverable.

Moving forward, development teams must consider the following trends to maintain a competitive advantage in a fiercely expanding market.

AI Finds its Footing in Business and QA

The rise of automation and Artificial intelligence was predicted in last year’s trends. Nevertheless, it has been included this year as companies will analyze how artificial intelligence applies to their business. According to The World Quality report, 55% of respondents said that this was their main problem with setting up AI projects.

With regards to QA, more companies are expected to adopt machine learning techniques in areas such as predictive analytics (predicting future outcomes of the testing process based on historical data), defect analytics (highlighting at-risk areas of an application) and test suite optimization (identifying redundant test cases).

The use of AI in testing might require newer skills which will eventually lead to organizations creating new roles for AI QA strategists, data scientists, as well as AI test experts in QA and testing teams.

Instant Apps Take the Spotlight

Instant apps are native mobile apps that are smaller in size. Thus, more convenient for the user who is no longer required to download a standalone app.

The demand for better user experiences and shorter load times are constantly increasing.

Google’s introduction of Android App Bundles allows developers to modularize their apps and deliver features on demand; this will make more organizations adopt the Instant Apps approach.

QA Decentralization

The QA and testing department has been fragmented as a result of the transition to agile and DevOps. QA is now embedded into cross-functional teams. So, quality is dependent on the team members’ skills and their responsibility to integrate testing into their product life-cycle.

Continuous Improvement

The trends mentioned above have contributed to the rise in the adoption of Agile & DevOps over the past few years. Testing is an early part of the development process. More companies will adopt more agile/DevOps models to help them release faster and receive quick feedback. Other companies will take it a step further by adopting approaches such as continuous testing and continuous monitoring.

An attitude of “continuous improvement” will enhance the overall performance and quality of products by teams.

Quality Engineering over Quality Assurance  

QA professionals will enhance their technical skills and include some automation-related work organized by quality engineers. The role of Quality Assurance will deviate to implementing the latest technologies to boost the speed of quality checks. This is a trend that will come into play in the coming years.

Big Data Testing

With big data testing, testers have to verify that terabytes of data are successfully processed. Additionally, the aggressive increase in quantity is making it more tasking for companies. More likely, QA will have to deal with validating the quality, accuracy, and consistency of huge datasets.

These trends above demonstrate the crucial transformation both companies and QA Automation Testing Services is undergoing. The expectations of consumers will continue to shoot up. Organizations must adapt and deliver if they must remain in the front line and grow beyond 2019.
