With digitization, open banking application program interface (API) regulations, and omni-channel customer experience becoming the high-priority initiative for most organizations, the core or mainframe renewal, and APIficiation is necessary to ensure the success of these initiatives. Creating a successful API is not easy and creating APIs for mainframe is even more troublesome, because it requires deep integration and data-exchanging capabilities between legacy and newly written applications in the API digital world.
Existing mainframe systems have been built up over the years and encapsulated enormous valuable business logics and data. These rich and mission-critical sources of business services and information are critical for digital transformation. As enterprises address business transformation, they will have to make their mainframe data and applications available as APIs in the total digital solutions to be able to extend their digital reach for consumption through social, mobile, analytics, and cloud (SMAC) channels.
We leverage a number of in-house tools and frameworks to accelerate enablement of new user experiences and functionalities through microservices and API’s for clients running their core on mainframe, in an incremental manner.

As clients embark on simplifying and optimizing their existing mainframe footprint and migrating out of mainframe, having a comprehensive decommissioning strategy is essential to ensure that unused or migrated applications are actually retired and the data is archived for any future usage.
Our decommissioning solution is a step-by-step approach providing a comprehensive framework, to achieve speed-to-value, economies of scale, simplified landscape, enable agility, and reduce run cost.
The use of tools and accelerators help in the process of data analysis, migration, and archival during the decommissioning exercise. With Infosys, clients benefit from the following:

Most organizations’ mainframe workloads consist of batch processes that could be classified into one or more of these categories:
Besides periodic processes, reporting and data related jobs are medium to low value to businesses and are expensive to run on mainframe. We help clients identify and offload workloads on the most suitable platform, deliver better performance, and bring the costs down significantly, with leaner and lighter mainframe.

Migration of Mainframe Batch Workloads to ETL Platforms
Mainframe re-hosting enables organizations exit legacy infrastructure, while retaining the capabilities of scalability, resilience, availability, and low-cost. This approach is suitable for enterprises that still see a great value in their existing applications and at the same time, find optimizing costs as the biggest driver to modernize.
Re-hosting refers to 'lift and shift' strategy of legacy applications and data to an emulation platform empowered with specialized re-hosting software such as Micro Focus Enterprise Server, TmaxSoft OpenFrame, Oracle Tuxedo ART, Raincode, and modern databases. Apart from reduction in total cost of ownership (TCO), re-hosting enables organizations to extend their IT capabilities through integration with multiple enterprise products and solutions.

TidalScale based Re-hosting
While re-hosting is a great option for simplifying IT landscape, it is not suitable for organizations with large workloads —upwards of 5000 million instructions per second (MIPS), running on mainframe. While re-hosting software can only scale up vertically, the ones that can scale horizontally have not been proven capable of handling large workloads.
At such instances, we enable organizations create and run large virtualized infrastructure using TidalScale – which can easily support and run extremely large workloads. TidalScale Software-Defined Servers are self-optimizing, use standard hardware, and are compatible with all applications and operating systems. They can deliver in-memory performance at any scale.

Re-Engineering Legacy Systems to Next Generation Architecture
When the existing functionality and processes implemented on mainframe are no longer able to support the newer business model and functionality, or are difficult and expensive to scale, re-engineering to a cloud native architecture becomes a high potential modernization option.
This creates a new application with similar performance and re-imagines user experience and new business functionality, typically done using cloud-native techniques, leveraging micro-services, containers and decoupling; allowing customers to take advantage of the scale, innovation and security of the cloud.
Re-engineering implementation and delivery is accelerated using Infosys as well as partner platforms and tools. Infosys helps clients with:

DevOps for Mainframe
DevOps has been evolving over the last few years and at its most basic; it is the process of bringing development, testing, and operations together to share processes and procedures. On mainframes, it requires a huge mindset change as the traditional mainframe developers are used to quarterly / monthly releases and are not used to continuous delivery. Continuous delivery is an approach through which software passes from the workstation to production environment so that value can be delivered to stakeholders with as little delay as possible.
In order to take this forward to our clients, we have developed a lighthouse program in accordance with the consulting team. This program will define the agile, continuous integration (CI)/ continuous deployment (CD) processes specific to mainframes and provide an enablement plan to shift from the traditional waterfall approach to new ways of working.
We will leverage its unique DevOps platform in accordance with partner tools from Compuware, Microfocus, and IBM to implement DevOps on the mainframe for its clients.
