Meticulous measures & time help avoid stormy cloud migrations
By Clinton France | Dec 21, 2018
Take your time. Making the migration to the cloud shouldn’t be rushed or taken lightly. As we’ve learned from the news earlier this year about UK-based bank TSB, poor planning and faultily executed migration results in a big headache for everyone.
The entire event certainly didn’t go unnoticed. In fact, Forbes reported on the disastrous April migration attempt as a case study of what not to do when making a migration.
In April, TSB moved to migrate customer records from its aged legacy IT infrastructure to a cloud platform. The migration didn’t exactly go as planned. In fact, the migration resulted in nearly 1.9 million people (including TSB customers) being locked out of their accounts, bank cards being declined, businesses not being able to pay their employees, property purchases falling through, unauthorized transactions, and more.
The service and connectivity failures continued for almost a month following the migration. In Forbes writer Jason Bloomberg’s words: “The result was a complete and utter fiasco.” After further digging by a House of Commons Treasury Select Committee, it became clear that TSB’s rather speedy migration planning phase and truncated testing phase played a part in its turbulent move to the cloud.
TSB’s April mishap and other recent stormy cloud migrations highlight a need for enterprise organizations to conduct more meticulous pre-migration planning. Results of a cloud migration survey released earlier this year by Dimensional Research show that nearly 75 percent of participants reported cloud migration projects taking a year or more longer than expected. Further survey data reported projects running late or over budget mostly due to poor planning and inaccurate data, as well as a lack of clear and objective TCO goals.
There’s a better way to migrate to the cloud. We’re seeing a new focus on cloud migration planning fueled by testing measures, which can provide an accurate picture of application requirements and the underlying infrastructure service. Performance and functionality testing defines a set of baseline performance results, which can be used to determine the proper sizing, configuration options, and service objectives for a migration. These same measures have also become the basis for the TCO models and, ultimately, cloud performance baseline measures to ensure financially optimal and operationally effective platform service.
Krystallize Technologies is leading the way in the industry by specializing in cloud performance measurement. Krystallize is also helping enterprise IT teams gather actual service throughput measures to track acceptable performance across their unique workloads in real time. Intelligent measures gleaned from CloudQoS illustrate a baseline target of best-fit, best-cost performance recommendations for cloud service during pre-migration planning or during post-migration service assurance and optimization.
