OpenLegacy Microservices

Considering the power of microservices? We can help.

Do you have an immediate need to quickly create digital services, but have longer term goals of simplifying your legacy architecture or expanding your Cloud strategy? Interested in future-proofing your investment?

Microservices aren’t new, but are becoming a more critical part of many enterprise cloud and digital strategies. Touted by analysts like Gartner and Forrester and mega-organizations like Amazon, NetFlix, Nike, and eBay, microservices are finally getting much deserved attention in the technology stack.



What is a microservice and a microservice architecture?

Before we get into some best practices in implementing microservices, let’s take a step back and define what is a microservice.

A microservice is a software component that is decoupled and deployed from your legacy system to run a single business process or individual service. It integrates with well-known interfaces (like an API) and owns its own data storage.

A microservice architecture leaves legacy systems intact for as long as you wish, yet offers freedom to use the microservices for rapid innovation and deployment anywhere, especially the Cloud.

Using tools like OpenLegacy’s microservices edition, building microservices becomes easy and you can even get microservice-enabled APIs from legacy systems in minutes.

How to best use microservices to modernize your legacy system

The architectural style you choose can greatly impact your development, innovation, and business capabilities.

Compared to a monolithic architecture, microservices are easier to build, test, deploy, and update. Red Hat believes it is the answer to the question: how can my business react faster to new demands, rather than being stuck in the multiyear "death march" of traditional software development? Now, different parts of your development team can work concurrently on your products, in an agile manner, and deliver value to your customers immediately, increasing your business capabilities.

The key to digital transformation success is finding ways to access the mission-critical data stored on legacy systems and putting it to work in agile projects.

There was a time when service-oriented architectures (SOA) promised to do just that.

But instead, SOA added another layer of complexity to monolithic architecture. Microservice architecture, on the other hand, bypass the complex mesh of interconnected subsystems that makes up your SOA and gains direct access to the data points in legacy systems.

A microservice architecture combined with APIs makes even the most complex applications easier to develop.

Microservices make testing faster and easier because each unit is self-contained with interfaces to each other. You only need to test the ones that changed. Each microservice is a small, separately loadable entity so deployment is simpler.

By contrast, traditional, monolithic applications require the entire system to be built, tested and deployed together so releases are less frequent and developers wait for the process to be completed. This is a big reason why developing enterprise applications is often seen as a massive effort.

The benefits of Microservices


iT benefits business benefits
Improve modularity making an application easier to understand, develop and test Build new products and offerings at a fraction of the time & cost
Reduce interdependencies, so updates don’t have unintended consequences Quickly iterate and evolve to changing market needs
Enables small teams to develop, deploy and scale services independently Deliver a unified user experience regardless of channel, device or location
Supports agile, DevOps, continuous delivery and deployment No more house of cards where one innovation causes unintended issues in other applications
Enables large enterprises to create a global API strategy Transform IT from a business anchor to an engine accelerating forward
Allows more efficient and cost-effective scaling of specific services Reduce the cost & time required for larger legacy migration initiatives, so you have more It resources available - sooner
Accelerates future legacy migration projects since APIs are already microservices  

Eight reasons to choose OpenLegacy for microservices.

microservices Create an application and an API at once

One tool. One step: Create an application and an API at once. OpenLegacy’s Microservices Edition creates microservices as an API that has the application, rules and security built-in. In one step, you can create a legacy API and expose business processes as microservices. One tool, one step, and a giant leap for your organization.

microservice best practices No modifications to legacy systems

No modifications to legacy systems. OpenLegacy generates standard, lightweight code for microservices, and does not require any modifications to the backend mainframe applications. In this case, we like being called a ‘lightweight.”

micro-services No middle layers

No middle layers to mess with. OpenLegacy’s architecture does not involve any middle layers such as ESBs and MQ, thus shortening the development cycle and leading to significant cost savings.

Avoid decentralized monoliths

Avoid decentralized application monoliths. Our approach is quite different than other typical types of “Integration microservices” offered by other vendors, where you essentially end up with a “decentralized monolith” where microservices are still dependent on each other. Who needs that?

Automatically create microservices

Automatically create microservices, really! Automatically generate a microservice as a self-contained standard Java component. It features a standard interface which deals with a small problem domain and for data storage it has an SDK which refers back to a business process or data on the legacy core applications.

microservices Decouple and standardize

Decouple and standardize. OpenLegacy provides an automated and standard way of functionally-decoupling a monolithic core application by creating a microservices architecture on top of it, consuming it as a data-store but leaving it unchanged. Fewer changes, fewer problems.

microservices architecture Remove the chains and be free at last

Remove the chains and be free at last. With decoupled microservices, you can launch the digital services you need now, while also having the freedom to migrate off your legacy system and/or expand your Cloud strategy in the future. Plus, every new microservice reduces your future total cost of ownership.

microservice best practices stunning performance

Oh, and also stunning performance. Since we avoid complex layers of architecture, our microservices are extremely fast. In fact, one of the largest banks in the world reported that transaction response time improved by 70X.

Choose us now, or after you’ve spent a truckload of money and still got nowhere

Why not give us a shot -- just one conversation. We are winning the big deals from mammoth sized global companies because we found a better way to do legacy APIs – and also create microservices.

While it is a shame we can’t use his name, a CEO of a very, very large bank recently said to us he had spent “dozens of millions of dollars” working with one of the world’s largest legacy transformation vendors and after a year they still had “a huge backlog of unimplemented services.”

They shifted gears and chose OpenLegacy. Once the discovery process was complete, OpenLegacy delivered 5 APIs as microservices in 3 days. A documented fact.

The decision is: where will you put your money and how big is the truck you need to drive? Do you want to throw good money after bad?
