Using automation to modernize mainframe applications will bring a codebase to today’s common coding standards and architectures. But in many cases, modernization to an application’s functional equivalent isn’t always enough. Organizations can do more to make their modern code more efficient and readable. By building refactoring phases into their modernization projects, organizations can eliminate the Pandora’s box of dead or non-functional code that many developers don’t want to open, especially if it contains elements that just don’t work.

Using TSRI’s automated refactoring engine, remediation was complete in an hour.

What is Refactoring and How is it Used?

Refactoring, by definition, is an iterative process that automatically identifies and remediates pattern-based issues throughout a modernized application’s codebase. For example, unreferenced variables or unnecessary redundant snippets could exist throughout the application. This scan, known as dead/redundant code refactoring, will find repetitions of any of this unusable code to flag, then remove it from the codebase. One of TSRI’s current projects found 25,000 instances of a similar issue that would have required 15 minutes of manual remediation per instance—not including the inevitable introduction of human error that would require further remediation. The number of development hours would take more than a year for a single developer to complete.

Using TSRI’s automated refactoring engine, however, remediation was complete in an hour.

Calling refactoring its own post-modernization phase is, in some ways, misleading. Refactoring typically occurs all the way through an automated mainframe transformation. As an example, in a typical COBOL or PL/1 mainframe modernization, TSRI would refactor the code from a monolithic application to a multi-tier application, with Java or C# handling back-end logic, a relational database layer through a Database Access Object (DAO) layer, and the user interface (screens) modernized in a web-based format. Believe it or not, many legacy applications still run on 3270 green-screens or other terminals, like in the graphic below.

Once the automated modernization of the legacy application is complete, the application has become a functionally equivalent, like-for-like system. However, any deprecated code, functions that may have never worked as planned, or routines that were written but never implemented will still exist. A process written in perhaps 1981—or even 1961—may have taken far more code to execute than a simple microservice could handle today.

Situations like this are where refactoring becomes indispensable.

Where to begin?

Before a formal refactoring process can begin, it’s important to understand your goals and objectives, such as performance, quality, cybersecurity, and maintainability. This will typically mean multiple workshops to define which areas of the modernized codebase need attention and the best candidates for refactoring, based upon the defined goals. These refactorings will either be semi-automated (fully automated with some human input) or custom written (based upon feedback from code scanners or subject-matter experts.)

The refactoring workshops can reveal many different candidates for refactoring:

• Maintainability: By removing or remediating bugs, dead or orphaned code, or any other anomalies the codebase can be reduced by as much as one third while pointing developers in the direction of any bugs in need of remediation.
•  
• Readability: Renaming obscure functions or variables for a modern developer to fit within naming conventions that are both understandable and within the context of the code’s functionality.
•  
• Security: Third-party tools such as Fortify and CAST can be utilized to find vulnerabilities, but once found they need to be remediated through creation of refactoring rules.
•  
• Performance: Adding reusable microservices or RESTful endpoints to connect to other applications in the cloud can greatly improve the efficiency of the application, as can functionality that enables multiple services to run in parallel rather than sequentially.

What are the Challenges?

• Challenge 1: One reason refactoring must be an iterative process is that some functionality can change with each pass. Occasionally, those changes will introduce bugs to the application. However, each automated iteration will go though regression testing, then refactored again to remediate those bugs prior to the application returning to a production environment.
•  
• Challenge 2: The legacy architecture itself may pose challenges. On a mainframe, if a COBOL application needs to access data, it will call on the entire database and cycle through until it finds the records it needs. Within a mainframe architecture this can be done quickly. But if a cloud-based application needs to call a single data record out of millions or billions from halfway across the world (on cloud servers), the round trip of checking each record becomes far less efficient—and, in turn, slower. By refactoring the database, the calls can go directly to the relevant records and ignore everything else that exists in the database.
•  
• Challenge 3: Not every modernization and refactoring exercise meets an organization’s quality requirements. For example, the codebase for a platform that runs military defense systems is not just complex, it’s mission critical. Armed forces will set a minimum quality standard that any transformation must meet. Oftentimes these standards can only be achieved through refactoring. A third-party tool like SonarQube in conjunction with an automated toolset like TSRI’s JANUS Studio^® can be utilized to discover and point to solutions for refactoring to reach and exceed the required quality gate.
•  

In conclusion, while an automated modernization will quickly and accurately transform legacy mainframe applications to a modern, functionally equivalent, cloud-based or hybrid architecture, refactoring will make the application durable and reliable into the future.

Modernization of High Value Assets (HVAs) and software systems is more urgent than ever. In the past year, tens of millions of U.S. citizens have leveraged critical online systems to manage their livelihood and health during the COVID-19 pandemic. With such a heavy reliance on these systems, now is the time for the federal government’s critically important HVAs systems to keep up with citizens’ growing needs.

The Technology Modernization Fund was established in 2017 to support government and civic agencies to bring their critical software infrastructure into the modern age. On May 12 of this year, President Biden issued a comprehensive executive order that gave direction to federal departments and agencies to strengthen the government’s cybersecurity posture. The order establishes a requirement to modernize systems and implement stronger cybersecurity standards by moving agencies and their contract partners to secure cloud services and a zero-trust architecture, which uses identity management protocols to verify that every user of a system interacts with the appropriate levels of security access. This order also mandated deployment of multifactor authentication and encryption.

According to Federal Chief Information Security Officer Chris DeRusha, the White House is pushing federal agencies toward a “zero-trust paradigm.” With the pressure on, many agencies are struggling with the magnitude of such an undertaking and are, justifiably, fearful of the perceived security and down-time risks associated with modernization.

Modernizing an HVA doesn’t have to be risky

Using a graceful, automated approach to leverage modernization solutions can result in a very low risk modernization. By implementing a step-by-step cloud migration while keeping legacy systems running in parallel, an automated modernization can happen quickly, safely, and reliably.

TSRI has over 25 years of experience undertaking migrations of this kind (see below).

At AWS re:Invent 2020, Amazon Web Services (AWS) unveiled plans for a new “Mainframe Migration Competency” and announced that TSRI has been identified as a launch partner! AWS recognized that TSRI’s solution — which provides near-100% automation and cloud-specific refactoring — are a huge benefit for organizations seeking reliable, low-risk, and rapid migration to the cloud. Furthermore, TSRI’s proven track record, which includes hundreds of successful modernization projects over more than 25 years, meant that TSRI would be a reliable and knowledgeable technology partner for AWS customers.

From AWS:

“Recognizing the complexity of a mainframe migration, our customers seek proven methodologies, tools, and best practices to empower successful migrations. The AWS Partner Network (APN) plays a critical role in these efforts by providing proven technology products and services for customers’ mainframe migrations.”

TSRI’s model-based solution transforms even very large (tens of millions of lines of code) legacy systems written in languages like COBOL, Fortran, PowerBuilder, Ada, MUMPS, VB6, and more than 30 other languages, into modern applications in cloud-native target architectures. The output is a modern multi-tier application that takes advantage of cloud utilities and scalability.

Now is the time to modernize for the cloud. According to AWS, “more than 70 percent of the Fortune 500 companies still run business-critical applications on mainframes, and many companies and institutions still possess legacy mainframes in their data centers. As a result of constantly evolving customer needs, the demand for modernization has accelerated as companies require increased agility to meet those needs.

“Due to the slow development cycle of mainframes, more companies are migrating to the cloud to enable rapid development and innovation. Furthermore, as mainframe subject matter experts retire and leave the workforce, these companies face an increasing skills gap.

“Coupled with high upgrade and development costs and expensive usage fees, CIOs with mainframes they must maintain are well aware of the business risks to their enterprise. As a result, a growing number of companies are looking to modernize and migrate their mainframe workloads to Amazon Web Services. These migrations enable companies to realize business benefits like an average 70 percent savings in IT infrastructure costs.”

See the AWS blog for more.

We’re excited to start the modernization journey with any organization looking to get off their mainframe and on to AWS!

Perhaps you’ve seen your competition pull ahead. Maybe your customers have become frustrated with their experience as they interact with your systems. Possibly, you’ve even experienced a security breach. You know your legacy systems need to move into the 21^st century, and perhaps you’re struggling to decide how to move forward. Whether you want to face it or not, now is the time to take a hard look at modernizing your digital infrastructure.

According to salesforce.com, “while there may be a multitude of reasons for a business to undergo digital transformation, it mostly boils down to survival. Digital transformation can be risky and expensive, so it’s often a necessity for businesses that want to survive and outlast the ones that failed to evolve.”

And then there’s the expense: Daniel Newman at The Future of Work suggests that as much as 80 percent of an IT budget can be spent on maintenance. Modernizing legacy systems—even incrementally—can help a company see its capabilities leap forward by using the cloud to integrate automation into standard business processes. John Brandon at techradar.com suggests that “some of the most disruptive technologies—such as machine learning, voice bots like Amazon Alexa, and artificial intelligence—are helping to automate mundane tasks and improve how a business runs.”

These technologies run on data. In this new era of computing, the businesses that truly succeed will be the ones that put an emphasis on their data. If they haven’t already, legacy systems with limitations on their data will fall behind, especially when introducing machine learning and AI into the mix. At the same time, the data and infrastructure that have kept older systems going for so long can’t just be switched off, and freezing the systems as teams write and develop its replacement will push customers away.

Modernization effectively overcomes these risks to your organization by opening up the possibilities that an older codebase wasn't designed to handle.

“Taking inventory of what still works and what doesn’t allows companies to identify which processes are no longer relevant,” writes Newman. “Only applications deemed critical to business are then modernized; the others are simply retired, saving time and money on maintenance.”

When you decide to replace or reconfigure your legacy system, you can decide between any of these modernization options:

New Application Development. Replicate your legacy system by writing entirely new code. Your team will manually develop your new system using current coding practices with modern interfaces, and support for current technologies. This option is very expensive option, and it’s generally only usable to set a baseline for future development. You’ll incur expenses that can be as high as the original project, risk levels are similar to a typical “waterfall” project, and there are high likelihoods of time and budget overruns.

Extend/Surround. Many organizations currently opt for this method. The development teams or consultants encapsulate the legacy system in coding containers that provide APIs and tack-on integration with other systems. While the solution may work, you will have a patchwork of code, often in multiple programming languages, that gradually increases technical debt and incurs added maintenance costs. While this situation defers replacement, it will likely be costly in the long run.

COTS/SaaS. Both common off-the-shelf (COTS) solutions or cloud-based SaaS systems enable you to migrate to a less expensive and more modern architecture, but costs can easily escalate. The new system will require customization and ongoing licensing costs. Such a migration could create ripple effects on other systems and cause you to incur other costs from conforming to a completely new platform with unknown attributes.

Automated Modernization. A careful translation of code by a team of expert external engineers creates a new, modern application based upon the logic and behavior of the original. The process will include varying degrees of automation, which increases accuracy while decreasing costs. Modernization will likely incur the least risk and expense of any of these options.

Replacement of aging systems is becoming increasingly urgent, and as programmers of many of these older systems retire, replacement costs will continue to rise. An automated modernization program will likely yield the least expensive and most flexible alternative for stable, long-term performance.

Nearly everyone wants speed, efficiency, and accuracy—especially when it comes to software applications. As companies modernize their legacy codebases and migrate to the cloud, one of the best ways to achieve top performance is to create containers for modernized code.

Code modernization has become increasingly important as we move toward integrated cloud-based and virtualized software environments. While the original legacy code was written to meet the needs of the business at that moment time, modernization of code permits these legacy applications to meet the needs of today’s organization while retaining the integrity of the original business logic. Software developers can then focus on innovation rather than maintenance. Modernization makes it possible to meet the demands of today's infrastructure requirements without high cost or compromises in security or functionality. Companies looking to expand services, access improved processes, and use resources more efficiently will need architectural changes. Bringing these trends together, containerization under Docker and Kubernetes has created a new model for application deployment that provides numerous advantages to program operation and interoperability but requires special accommodation.

Containers provide consolidation benefits by permitting application instances to be stacked in larger virtual machines. Containerization improves efficiency, security, and reduces software licensing. It reduces complexity and ensures application portability, but the boost to protecting an organization’s systems at a time when only 56% of companies are integrating security into their technology strategies cannot be understated, according to Advanced’s 2020 Digital Business Report.

To take advantage of not just the security inherent to containerization, but the potential of having systems that can be ready for the next big advances in computing, applications must be modernized to externalize APIs and microservices. It is also important to ensure proper function within a containerized environment. Modernization transforms legacy applications to operate efficiently, reliably, and securely within the new environment with identical performance to the original application.

The Three-Step Approach: Transform, Cloud-Enable, Containerize & Deploy

When thinking about modernization, organizations can take a three-step approach based on TSRI’s experience in all forms of legacy code transformation, including migration to cloud services and containerization, to reduce risk and increase success:

1.         Migrate legacy monolithic code to a service-oriented environment. This includes updating language from COBOL to Java, JavaScript, or C#, changing databases, and enabling microservices. At this step of the process, the migration also begins to abstract underlying services from the application.

2.         Integrate service-oriented applications with native cloud services. This includes re-orienting code from WebSphere, DB2, or other legacy platforms to Apache Tomcat, Amazon RDS, or other modern platforms, for example. Upgrading to incorporate the latest native architectural interfaces ensures that applications will tightly integrate with the new environment, and ensures easier updates in future.

3.         Transform native cloud to Docker containers. The movement to containers provides additional architectural abstraction and improved integration of applications within the cloud.

As with any kind of migration and modernization, organizations need to assess, tune and optimize their applications for suitability and to ensure that applications will perform adequately within the container environment without infrastructure issues that might arise from coding anomalies.

The key to a successful migration is to evaluate and model the underlying legacy code logic and to pinpoint the areas that require adaptation to the new environment. Not every application has a natural and hazard-free path to a cloud-based containerized solution. Knowledge of container operations such as ephemeral storage and parallelization issues is extremely important in managing this transition. The transformed code must also be optimized to meet the needs of its new environment.

In the case of migrating and modernizing mainframe systems to the cloud, fully automated refactoring technologies such as TSRI’s JANUS Studio® toolset transform legacy applications to cloud-native applications for containerized deployment on multiple cloud providers, including a practice devoted specifically to AWS. TSRI’s model-based solution transforms even large legacy systems written in languages such as COBOL, Fortran, PowerBuilder, Ada, MUMPS, and VB6 into modern applications in cloud-native target architectures.
