Microservices & Containers


In the age of Digital Transformation, customers have become more and more reliant on web and app-based activities. All the while, businesses are shifting to faster and more advanced technologies to stay relevant and to service the shift in market. Moving away from Monolithic architecture based systems towards Microservices and Containers has proven to be the best and most efficient way to keep up with the shifting market and to always stay on top of things.  

But let’s not get ahead of ourselves. 

What are Microservices?

monolith vs microservices architecture

Microservices Architecture is a software development approach where the software application is modular and created through independent components. Each of those components is built, tested, deployed and operates totally independently of the other components.  

 An approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. “ James Lewis and Martin Fowler (2014)

What are Containers?

Since microservices are self-contained, independent application units, with each fulfilling only one specific business function, they can be considered small applications in their own right. What would happen if you created a dozen microservices for your app? What if you decided to build several microservices with different technology stacks? Your team would soon be in trouble as developers have to manage even more environments than they would normally do with a traditional monolithic application. There’s a solution though: use containers to encapsulate each microservice.

Containers are lightweight, standalone, executable packages of software that include everything needed to run an application, but use the underlying operating system from the host the container resides on.

Microservices over Red Hat OpenShift

Red Hat OpenShift is the industry’s most secure and comprehensive enterprise-grade container platform based on industry standards, Docker and Kubernetes. The platform helps enterprises build applications faster, deliver and scale across hybrid cloud environments using microservices and containers.

It is the Kubernetes platform that provides a trusted foundation for the on-premises, hybrid, and multi-cloud deployments. With automated operations and streamlined lifecycle management, OpenShift empowers development teams to build and deploy new applications and helps operations teams provision, manage and scale a Kubernetes platform

With Microservices and Containers in full launch, banks worldwide have made extensive strides towards more customer-centric profiles and have had an immense 531% ROI over a 5-year period. Some of banks being Emirates NBD, Deutsche Bank, Macquarie Bank and many more. In 2020 Export Development Bank of Egypt(EBE) has joined the impressive roster of banks and moved from Monolithic architecture towards the modernized Microservices and Containers using the latest technologies and services provided through Red Hat Openshift and Sumerge.

Benefits of deploying Microservices Architecture

Time to Market

Microservices architecture enables teams to apply DevOps practices to speed up their development process since each feature is built, tested and deployed independently thus enabling teams to ship new features quickly and independently of each other. Also, due to the nature of the architecture, multiple teams can work together in parallel, thereby also increasing the frequency of releases per month.


At the infrastructure level, each microservice is scaled and managed on its own. There is no need to scale the whole system in situations of peak time and increasing load. In fact, only the microservices experiencing a high load are scaled. This is also done automatically without human intervention via auto-scaling capabilities and self- healing.

Guaranteed Up-time

With the right microservices architecture, it’s almost impossible for the whole system to go down. Since each microservice is built, deployed and managed independently and is totally isolated at runtime, the whole system can therefore never go down. Should a microservice crash, this will only impact its own functionality, the rest of the system will behave normally.

No Vendor Lock

Microservices architecture and its principles are based on open standards and are strongly backed up by the open source community. Almost all commercial microservices platforms follow these open standards which makes it easy to migrate from them whenever necessary. So, by design, microservices have standard based APIs which makes it easy to extend and even use different programing languages and technologies.

Resilience & High Availability

What happens when a microservice fails unexpectedly? Not only does this not impact upon the whole application runtime, the platform also detects the failure and restarts the microservice. This is what we call “self-monitoring” and “self- healing”. Kubernetes, OpenShift Container platforms or orchestrators have the capability to automatically detect failures and self-heal. These capabilities measure the system’s health thereby ensuring resilience and high availability.

Dynamic Talent Pool

With microservices, it’s easier to onboard new team members as well as hire software engineers with different coding backgrounds. Instead of a large complex monolithic system that needs a lot of knowledge transfer and code handover before a developer can start participating in the platform, in a microservices world it’s a lot easier since the developer is building and deploying simple microservices isolated from the complexity of the rest of the platform.
