Cloud Migration: From Monolith to Microservices | @CloudExpo #Microservices

With web and mobile platforms established this then makes possible the full three-tier scope of ADM transformations.

Cloud Migration Management (CMM) refers to the best practices for planning and managing migration of IT systems from a legacy platform to a Cloud Provider through a combination professional services consulting and software tools.

Legacy Transformation and Modernization
A Cloud migration project can be a relatively simple exercise, where applications are migrated ‘as is’, to gain benefits such as elastic capacity and utility pricing, but without making any changes to the application architecture, software development methods or business processes it is used for.

There may be a clear business for doing so, such as the hardware platform becoming obsolete, however the organization overall won’t realize any additional benefits, there is no business transformation as part of this move.

With senior executives potentially expecting broader strategic capabilities as a result of a move to the Cloud, it’s therefore important that clarifying this scope is the very first step in planning a Cloud migration, and the OMG’s Architecture Driven Modernization methodology is ideal for this purpose.

As the ADM ‘Horseshoe’ model articulates, and this Carnegie Mellon article, a migration project can be considered with three distinct tiers of scope possible, increasing the size and length of the project with an increasing level of associated business benefit.

This begins at 1) a Technical migration, meaning the application is migrated ‘as is’ to a new hardware infrastructure service without modification.

Breaking Innovation Gridlock – Harnessing DevOps and Microservices
Higher levels then include 2) Application and Data Architecture and 3) Business Architecture, meaning that as well as shifting platforms the application itself is also transformed and then furthermore, so is the business model that it enables.

As the horseshoe describes these increases in scope mean a larger project that takes longer, because each is delivering a larger scope of business benefits, impacting a larger group of stakeholders and requiring a larger business transformation exercise.

Exploring the nature of these benefits can help specify exactly what business executives are hoping to gain by moving to the Cloud, and this can be headlined by a theme of “breaking innovation gridlock”, described in this white paper from HP.

In short this described how most large enterprise organizations have a legacy application estate, made up of elderly technologies like mainframes running COBOL, that perform the core business processes of the organization and are thus central to the business value they provide, but because of their age have become rigid, inflexible and fragile business systems.

Due to the complexity of these environments and the lack of staff skilled in these technologies they essentially become untouchable black boxes; the CIO can’t take the risk of downtime by trying to make changes and due to their age their maintenance is very costly, consuming the majority of their budgets as HP describes.

Thus they have become trapped in a state of innovation gridlock, unable to afford investment in new digital-enabling platforms and unable to adapt legacy systems to offer new customer-centric processes.

Enterprise DevOps
Therefore although moving to IaaS can deliver benefits such as elastic capacity and utility pricing for infrastructure level components, this isn’t really of strategic value to most large organizations as they aren’t constrained in these areas.

Instead where the major business value will come from is modernizing this legacy environment, transforming the core enterprise applications to new Cloud-centric approaches so that innovation gridlock is broken and a faster cycle of development throughput is achieved.

A variety of tools are available that can automate the process of transforming legacy code like COBOL into their modern equivalents on Java and .net, meaning they can be re-deployed to private or public Cloud services and most importantly, then much more easily modified by software developers, setting the scene for an agile Enterprise DevOps culture and faster change cycle achieved through Continuous Deployment practices.

Furthermore leading edge Cloud architecture principles can also be utilized, such as ‘Microservices’. This means breaking up large monolith software, like mainframe systems, into an array of small self-contained services making it even easier to implement change at a faster pace. As described in our Microservices section pioneering organizations like Nike have adopted this approach.

Conclusion
An especially powerful aspect of these legacy transformation solutions is that they can also automatically generate the new code required for key features such as a web front-end and mobile client.

This would provide the foundations for achieving the enhanced functionality that senior executives are likely hoping for from their Cloud investments. As they seek to pioneer their digital strategies enabling ‘omnichannel’ access across web and mobile interfaces the IT team would previously have faced a considerable challenge achieving this goal when working with aged application environments.

By employing the full scope of Architecture Driven Modernization they can quickly accomplish this important capability while also transforming the environment so that additional innovative enhancements can more easily be engineered too on an ongoing basis.

With web and mobile platforms established this then makes possible the full three-tier scope of ADM transformations. Business executives can more easily build social communities around their core business processes, explore dynamic new mobile commerce scenarios, and so on. In short the only limitation of the innovative business models they might pioneer would be their imagination, not the IT estate.

"Cloud computing is certainly changing how people consume storage, how they use it, and what they use it for. It's also making people rethink how they architect their environment," stated Brad Winett, Senior Technologist for DDN Storage, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
Existing Big Data solutions are mainly focused on the discovery and analysis of data. The solutions are scalable and highly available but tedious when swapping in and swapping out occurs in disarray and thrashing takes place. The resolution for thrashing through machine learning algorithms and support nomenclature is through simple techniques. Organizations that have been collecting large customer data are increasingly seeing the need to use the data for swapping in and out and thrashing occurs ...
