How to Implement Hybrid Microservices ?
In the first post, we defined hybrid
microservices and discussed how they can fit into an enterprise landscape. Now,
let’s look at a detailed approach to implementing them.
Selecting the ideal monolith candidate
The best approach to a hybrid microservices solution
is to start with a use case that can be applied to real-time systems, scenarios
or applications in a new or existing business application stack.
This is an initial, but crucial step which must
be taken after careful analysis and deliberation, since the decisions made
about the “candidate” application will inform the overall strategy.
Splitting the monolith
One of the
most important steps in establishing a foundation for system design is splitting
a monolith into its logical and business components. These components will serve
as a blueprint for creating service components.
As part of
the split, it is important to employ a hybrid data source as a common, reusable
asset to be leveraged by each split component. The following diagram shows what
a typical monolith split will look like:
below shows how this initial split can be translated into a hybrid microservices approach:
Now, let’s explore the benefits that hybrid
microservices can deliver for our two stakeholders: the core business and IT.
- API-driven architecture : The greatest benefit of the individual components that form the foundation of an API-driven architecture is the ability to smoothly integrate a variety of business applications, including B2B needs.
- Improved API economy :
API economy is one of the critical success factors for modernizing any business, and establishing well-connected business data systems is one of the top items on any CIO/CTO’s wish list.
In addition, a strong API strategy and in-house API development capabilities can be leveraged for a variety of business revenue models.
By exposing APIs to vendors, customers and partners, you can establish smooth integration that enhances your business as well as others — and adds profit margin to their extended revenue models.
The core concept is very simple — we are paving
a way to reap the maximum benefits of microservices
architectural patterns and designs, but how we do it is crucial.
The goal is to create a cloud-native business
and API-oriented environment by employing microservices design and technology,
which can power a variety of business solutions within an organization.
With these technologies and design styles,
enterprises can stay ahead of the curve in this competitive and technology-driven
business era, and create a solid platform for future growth.
The key takeaway is to understand that every new innovation can offer a
piece of technological DNA that can be inherited and adapted for your IT
landscape. Solutions can take a variety of shapes, based on your organization’s
unique needs and business drivers.
Simply put, it’s up to us to understand what to
use and what to leave out.
