How to Migrate @UnisysCorp Mainframes to #AWS | @CloudExpo #CloudNative #SaaS #PaaS

Cloud providers like AWS have proven to be a viable option for running mainframe application workloads

Five Steps to Migrate Unisys Mainframes to AWS
By Craig Marble, Senior Director of Legacy Modernization, Astadia

Key Takeaways

- Cloud providers like AWS have proven to be a viable option for running mainframe application workloads

- The most effective method to exploit the value of Unisys mainframe applications and data is a transformative migration to modern systems frameworks in AWS, reusing as much of the original application source as possible.

- Execute a discover, design, modern, test, and implement cycle to move mainframe applications.

- Some mainframe migration tools can keep existing code in place, but expect to replace components and rethink data storage.

The Mainframe Conundrum
If you have a Unisys mainframe, you may be thinking that cloud computing isn't an option. You'd like to take advantage of all that cloud computing offers but don't think it's possible because it can't handle your transaction workloads, or the architectures are just too disparate to merge, or even that it's just plain too hard to do. I used to think the same thing. And until fairly recently, it was true. But cloud computing has quickly matured, as have the offerings of service providers like AWS, and it's now proving itself to be a viable option for running mainframe application workloads. With help from both AWS and mainframe experts, I've assembled a reference architecture for moving Unisys workload to AWS.  But before I go into what changed my mind, let's set the stage with a little history on Unisys mainframes and the evolution of cloud computing.

Unisys
Unisys can trace its roots all the way back to 1886 and American Arithmometer Company, which later became the Burroughs Corporation. The Unisys Corporation of today was formed in 1986 when Burroughs combined with the Sperry Corporation, which was originally founded in 1910 as the Sperry Gyroscope Company. Unisys and its various predecessor companies are credited with developing the first general-purpose computers, known as BINAC and UNIVAC - truly amazing achievements of the late 1940s and early 1950s that changed the world forever.

When Burroughs and Sperry merged to form Unisys, each company had its own line of mainframe computers, each with its own loyal customer base. There were attempts to unify the two architectures and their respective technologies, but the two distinct systems survive to this day. Unisys ClearPath Libra mainframes originated from the Burroughs line, while ClearPath Dorado's heritage is Sperry. Even though there are distinct differences between these two sets of mainframe technologies, they are in many ways very similar and share many of the same basic characteristics.

Little did anyone know at that time, advancements in computing architectures and miniaturization would lead to the ubiquitous nature of computers today. They're everywhere you look: cars, smartphones, tablets, even kitchen appliances like refrigerators, microwave ovens, and yes, even toasters. The average smartphone today makes the early mainframes look like children's toys; their computing power and speed far exceed that of their ancestors - for a mere fraction of the cost. An incredible evolutionary pace in a relatively short span of time.

Enter Cloud Computing
Flash-forward to around 1996. We began to hear about a new, revolutionary form of data processing called cloud computing. Many of us, including myself, were somewhat skeptical. Although we found it an interesting idea, we wondered whether it was just another trend du jour, and we took a wait-and-see attitude. Many of us figured it would fizzle out like other "revolutions" as soon as the next, shiny computing trend garnered attention. Certainly, those of us with mainframes thought it would have little impact on mainframe computing.

By the mid-2000s, it became apparent that cloud computing had legs. It did not disappear into obscurity like so many failed IT trends before it. Still in its infancy, it was nonetheless proven to be a reliable, cost-effective computing paradigm that had merit - for some. Companies like Salesforce.com began offering business functions such as customer relationship management (CRM) as a service. No longer did you need to invest in hardware and software to track customer data and interaction or to manage and automate sales activities. For a reasonable price, you could set up an account to do all this through any standard internet browser. No servers to buy and manage, no software licenses to track, no upgrades to plan and manage. Cloud computing was real and it had real benefits.

Cloud Computing Goes Mainstream
In 2006, Amazon introduced its Amazon Web Services (AWS) Elastic Compute Cloud (EC2) infrastructure-as-a-service solution, followed quickly by Microsoft Azure's Platform-as-a-Service offering in 2008. This seemed to solidify cloud computing's standing as a solution for more than just specific business needs, like CRM; it could also be used to run virtually any kind of Windows, Linux or Unix application. Using a pay-for-use model, you could migrate existing application workloads and development activities to AWS or Azure cloud environments. No more expensive data centers or co-location facilities to maintain, no more costly hardware upgrades to meet the demands of your expanding business, and through cloud replication, you could even satisfy your back-up and disaster recovery needs without an expensive remote mirroring facility! How awesome was that?

But again, those with mainframes felt the needs being met by their big iron couldn't possibly be matched by cloud computing. I mean, the high-volume transaction requirements alone were enough to make it a non-starter for enterprise needs. Not to mention the security implications of letting your sensitive data reside "somewhere" in the cloud. I admit I'm guilty of having had the same view. Until late one night in 2010.

If you'd like to learn more about this topic, I've done a further investigation in this report: Unisys to AWS Reference Architecture.

While some developers care passionately about how data centers and clouds are architected, for most, it is only the end result that matters. To the majority of companies, technology exists to solve a business problem, and only delivers value when it is solving that problem. 2017 brings the mainstream adoption of containers for production workloads. In his session at 21st Cloud Expo, Ben McCormack, VP of Operations at Evernote, discussed how data centers of the future will be managed, how the p...
The nature of test environments is inherently temporary—you set up an environment, run through an automated test suite, and then tear down the environment. If you can reduce the cycle time for this process down to hours or minutes, then you may be able to cut your test environment budgets considerably. The impact of cloud adoption on test environments is a valuable advancement in both cost savings and agility. The on-demand model takes advantage of public cloud APIs requiring only payment for t...
It has never been a better time to be a developer! Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service. FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected to start within milliseconds...

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.

For example, using spot instances and co...
The cloud era has reached the stage where it is no longer a question of whether a company should migrate, but when. Enterprises have embraced the outsourcing of where their various applications are stored and who manages them, saving significant investment along the way. Plus, the cloud has become a defining competitive edge. Companies that fail to successfully adapt risk failure. The media, of course, continues to extol the virtues of the cloud, including how easy it is to get there. Migrating...
For DevOps teams, the concepts behind service-oriented architecture (SOA) are nothing new. A style of software design initially made popular in the 1990s, SOA was an alternative to a monolithic application; essentially a collection of coarse-grained components that communicated with each other. Communication would involve either simple data passing or two or more services coordinating some activity. SOA served as a valid approach to solving many architectural problems faced by businesses, as app...
Some journey to cloud on a mission, others, a deadline. Change management is useful when migrating to public, private or hybrid cloud environments in either case. For most, stakeholder engagement peaks during the planning and post migration phases of a project. Legacy engagements are fairly direct: projects follow a linear progression of activities (the “waterfall” approach) – change managers and application coders work from the same functional and technical requirements. Enablement and develo...
Gone are the days when application development was the daunting task of the highly skilled developers backed with strong IT skills, low code application development has democratized app development and empowered a new generation of citizen developers.

We recently sat down with Nicole Forsgren, CEO and Chief Scientist at DORA (DevOps Research and Assessment) and lead investigator for the State of DevOps Report, to discuss the role of measure...
DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...

These days, APIs have become an integral part of the digital transformation journey for all enterprises. Every digital innovation story is connected to APIs . But have you ever pondered over to know what are the source of these APIs?

Data lakes is a term used to represent disconnected but relevant data that are used by various business units wit...
With continuous delivery (CD) almost always in the spotlight, continuous integration (CI) is often left out in the cold. Indeed, it's been in use for so long and so widely, we often take the model for granted. So what is CI and how can you make the most of it? This blog is intended to answer those questions. Before we step into examining CI, we need to look back. Software developers often work in small teams and modularity, and need to integrate their changes with the rest of the project code b...
