How legacy systems can live in symbiosis with the cloud.

by Jul 18, 2021Cloud Computing

The mainframe and legacy systems aren’t dead – most banking, insurance, and government institutions still run their legacy code on these types of servers, but they’re not immune from what this new era brought forth. By using a new type of integration software that connects different platforms together seamlessly while overcoming any latency or bandwidth limitations that could be caused by the distance between two disparate zones (cloud vs traditional), people are able to enjoy more flexibility when working in hybrid environments without having performance lag issues as well as being better equipped against espionage cybercriminals who would want access information stored remotely away from the physical location where data resides at all times nowadays.

How to create a scalable computing platform:

Through operating systems such as zLinux, mainframes are able to provide a highly scalable computing platform. Mainframes in the cloud context function similarly to how we view clouds today; they allow for multiple different business systems and their corresponding applications to be run from one source of power without any interruption or downtime. The relationships between these two technologies is critical because it allows businesses with smaller IT budgets access similar capabilities that companies traditionally have had – this opens up new opportunities where once there was only limited success possible due to lack of resources available for adoption by said company

The comparisons also fall short: mainframes cannot provide the latest technological features such as big data, artificial intelligence, auto-scaling and advanced monitoring.

However, they remain popular because of their ability to increase performance by up-tune systems for high-end transactions like AI programming or large-scale research projects.

Moving the IT industry to cloud

As the IT industry moves to cloud and distributed computing, many companies are finding that their mainframes remain on-premises. This has prompted a focus on improving speed, bandwidth, and security for how these environments connect with each other. With such capabilities already so mature in this field of study it begs the question: what more can be done?

Despite the evolution of technology, most companies rely on outdated interfaces that were created when distributed computing was just about to enter the market. It’s as if yesterday never ended for these enterprises because they still depend on old integration designs and methodologies even though there have been major improvements in security, bandwidth and speed over time.

How to modernise mainframes with the cloud using APIs:

There’s a new way to expand your software and make it more current, take advantage of increased connectivity options for data analysis or voice commands, connect seamlessly between environments without complicated setups: APIs! These are lightweight computer program interfaces that allow developers to create complex applications and devices in order to extract information from one system by using simple requests

There is also an increase in business app-building opportunities like never before because now you can use these same APIs not just within traditional systems but outside them too.

Businesses can now use software from mainframe vendors such as Software AG and IBM to identify the critical business capabilities of their applications. From there, they will be able to convert them into services accessible via APIs through modern TCP/IP application protocols. Yet, these opportunities need not remain untapped; instead one must simply make sure that he or she uses the right approach when creating those service API’s in order for it all goes according to plan

Are mainframes still relevant?

Mainframes are on a steady decline with nearly 50% fewer users than just 5 years ago! But don’t let this get you down – because we have an opportunity here! That is why using technology like Mainframe Business Services (MBS) by SoftwareAG allows us to take advantage of our legacy systems.

Tools to create web service APIs:

If you are looking for tools to create web service APIs, there is no shortage of options. However, two methods will be the most helpful: call-based APIs and terminal sessions that run in the background.

One way many developers build their services these days is by making calls from one program to another via REST (Representational state transfer)) or WSDL (Web Services Description Language). For those who need an explanation of what this means – basically, it involves sending messages over networks between software components on different systems using open standards called SOAP/XMLRPCs with HTTP as the transfer protocol. In other words “calling” programs more than anything else! This method can work well if all your communications take place within only one system.

Call-based APIs:

Program calls are popular because they are traditional and easily understood by programmers. Modernisation tools find COBOL or NATURAL/ADABAS code, converting the copybooks and parameters into a CORBA-like interface definition language (IDL). This IDL is then converted to Java, DOT NET, Web Services, IBM MQs etc., making it easy for modern programs to interact with these unmodernised old systems. The mainframe will be able to still consume cloud enterprise services and data by only requesting it from the distributed computing environment components. This also provides a more user-friendly interface with cohesive data objects for when they request this information back so that there is no confusion or potential errors in retrieving these pieces of important business intelligence.

Terminal sessions:

Background terminal sessions are only allowed to go one way, towards the users of a mainframe system. This means that all data scraped from screen is sent back through web services made available for use by these user terminals and their screens never refresh without being instructed to do so. The mainframe’s power is so great that it can still make a big impact without recent updates. It doesn’t need to be constantly patched and updated like other systems, which means your old code will work just fine for the foreseeable future with little fuss or bother. The legacy programs you’ve been running are already compatible – they were designed before modern technology became as prevalent in our daily lives as it has today – but now they’re available on another platform with more user-friendly features!

mWtech helps mainframe owners identify services from mainframe applications and consume these services, whether using the cloud or on-premises choices. We have extensive experience with creating web service APIs that enable legacy systems to be modernized 10 times faster than without them.

We are a leading provider of integrated IT solutions that enable customers to take their legacy applications online. mWtech believes in the strength and power of combining mainframes with cloud services, which can elevate each other’s ability for successful results on all levels – from security to scalability.
