Microservices Migration

To accommodate the increasing complexity of functional requirements, IT applications have embraced a variety of architectural patterns. Organizations must meet ever-changing business demands — from mainframe applications and client-server to service oriented architecture (SOA) and microservices.

Microservices architecture is a combination of successful and proven concepts of software engineering such as agile software development, SOA, API-first design and continuous delivery (CD). This architecture and organizational approach to software development is designed to accelerate development cycles, foster innovation and ownership and improve the ability to maintain and scale applications.


Despite technological advancements, 90 percent of business IT applications are legacy and what are known as “monolithic”. These range from mainframe apps where UI, business logic and data storage reside on machines, to client-server applications where layered technologies that support UI, business functionality and data are stored horizontally. Microservices architecture, on the other hand, divides the functionality into cohesive verticals by implementing a specific domain.

Product Quality.
  • Optimize Scalability: React fluidly with smaller, self-contained components
  • Achieve High Quality: Continuously and confidently develop and test
  • Maximize Resource Utilization: Utilize containers for efficient infrastructure consumption
  • Minimize Downtime: Perform isolated maintenance
  • Increase Reuse and Decrease Overhead: Encourage sharing on API driven architecture
Process & Culture.
  • Streamline Feature Development: Sprint faster to keep up with changing needs
  • Increase Innovation: Reorganize into domain specific, end-to-end service teams
  • Avoid Tool/Expertise Lock-in: Choose the best technique/technology for the specific problem
  • Adopt Existing Third-party Tools: Integrate easily into API driven ecosystems
  • Grow User Base/Expand Market: Extend capabilities to external parties
  • Enable Business Consumption: Solve small problems with measurable outcomes

Maintaining monolithic applications often proves challenging because it’s difficult to test and release millions of lines of code for tiny changes (in most cases only a few lines). But migrating to microservices is not as simple as it sounds. It requires a big change management process that often includes new team structures (to say nothing of altering the mindset of the organization!). To support the approach, technology stack must also be upgraded. In the microservices scheme, an application is built with a modular approach, making it scalable and easier to deploy. With the right tools, governance and automation in place, updates come much easier.

While Monolith has complexity in codebase, microservices poses the complexity of interaction between many services.

Pain Points

  • Code complexity & Maintainability
  • Deployment becomes the bottleneck, fear to change, lack of ownership
  • Failure dependencies
  • One size doesn't fit all, hard to scale out
  • Discrete hardware, 10% Utilization across servers
  • Hardware centric culture
  • Operations - infinite mails and tickets

Benefits / ROI

  • Composability / Reusability / Ease of maintenance
  • Autonomy of teams, culture of change, deploy more, deploy faster, deploy better. Ownership and DevOps culture.
  • Failure isolation and resiliency
  • Better scaling (out) and optimizations
  • Hardware aggregated, assign resource to service elastically
  • Software centric culture
  • Complete automated, run in pilot mode

    Cultural Challenges

  • You built, you run it

    Architectural Challenges

  • Dealing with asynchronicity
  • Cascading Failures
  • Discovery and Authentication of Services
  • Integration Tests

    Operational Challenges

  • Duplication of processes and tools
  • Complexity moves from components to interactions
  • Debugging across components
  • Deployment

Thankfully, current cloud-based distributed technologies alleviate the burden of managing monolithic applications by providing a platform to develop and deploy on a dime.

Three key Technology Drivers to Address Microservices Challenges.
Hardware Aggregation.

As you refactor one large monolith application into multiple independent services with their own services and data layer, you probably would end up having 25+ services, 50+ databases (Cache, Relational, NoSQL, Graph, Bigtable, Bigdata). Having them to deploy in Discrete Hardware (server by server), the deployment complexity itself will multiply to 50X at least. So, you essentially need to aggregate the hardware, say you aggregate your Compute/Network/Storage so that it looks like ONE big unit with combined capacity and you keep deploying your services & databases inside that aggregated cluster transparent of underlying Compute/Network/Storage. Thankfully, current cloud-based distributed technologies offer many avenues to aggregate hardware across data centers and geographies.

Containerization & Continuous Delivery.

As you transform monolith to microservices, your big X becomes 100 small x. If you deploy that 100 x as a layered stack in discrete servers in a different way, your deployment complexity would multiply to 1000X. To address this challenge, you definitely need to unify the delivery of services, make sure your services are delivered in the same way and they are staged to the production environment through some stringent quality gates. To unify the delivery of multiple services in the same way, Containerization play a big role and Containers along with the Continuous Delivery channel brings down your 1000X complexity to a factor of X.

Operation Automation.

An ideal microservices hosting platform is based on geographically spanned cluster and hardware agnostic. While this platform alleviates the burden of managing many servers, operating systems etc., it brings a new set of operational challenges like debugging, logs tracing, many processes and tools running in a single application. The operation management paradigm is shifted from managing Compute/Network/Storage and operating system to managing geographically distributed clusters and services management, their interaction. Thankfully, current cloud-based service discovery and cluster wide operation management technologies offer avenues to aggregate those operational challenges.

Essentially in a microservices ecosystem, you will aggregate, extent & automate. You will aggregate your hardware across DC’s and geographies, develop microservices, bigdata, IOT applications based on libraries and reusable services and continue to do cluster and services automation toward running everything in auto pilot mode.

One Key Cultural Driver.

Simply speaking the microservice world is “Solve small problems, with small teams with measurable outcomes vs solving 1 big problem with 1 large team.”
Since its small teams being responsible for end to end success, it’s much essential to establish a culture that “You built it, you run it”. Dev & Ops married, become DevOps. It means each employee are skilled to Develop small services and able to maintain its complete lifecycle. That involves a big change in structure & skills of the organization. Most of the microservices adoption will be successful if this cultural transformation is done right, we opine that it contributes 90% towards your success. A typical culturally changed organization will look like as below:
