Security Vulnerability Management 2019 Customers may have experienced intermittent degraded performance accessing SVM 2019 after the migration to Amazon Web Services.
Timeframe: August 18th 20:08 to August 18th 23:52 PDT
Investigations by Flexera engineers found the load-testing conducted prior to the migration to AWS was unable to reveal several code-level scaling issues in SVM 2019.
On Friday August 16th at 7pm PDT Flexera migrated SVM2019 from our datacenter in Copenhagen to multiple availability zones in the Ireland region of the AWS cloud.
This migration introduced a new scalable and immutable infrastructure with far greater capacity than the previous infrastructure. However, load-testing conducted prior to the migration failed to reveal several code-level scaling issues that were revealed on Sunday August 18th at 20:08 PDT once SVM2019 was under regular customer load.
In order to protect customer data and to minimize the impact of the scaling issues, the SRE team intentionally reduced the amount of customer traffic able to reach the SVM2019 application resulting in periods of intermittency while fixes were tested and then applied to the application in production.
At Sunday August 18th at 23:52 PDT CDT application service was confirmed restored.
· SVM 2019 Database was further optimized for the AWS environment
· Web servers were scaled up to utilize a smaller number of more powerful AWS servers
