The Platinum architecture is the last defined at MAA references<\/a> and is the highest level of protection that you can achieve for MAA. It goes beyond the Gold protection (that I explained in my previous post<\/a>) and you can have application continuity even version upgrade for your database.<\/p>\n

Platinum Architecture<\/h2>\n

The biggest difference for Platinum architecture is the usage of GoldenGate to sync both sides of the design. Everything used until now continues to be valid here. As I wrote before, basically, we have the same design of Gold (on every side) and synced with GoldenGate.<\/p>\n

As you can see above (and compared with the Gold architecture) the focus is beyond RPO and RTO, as you can see below in the old version of the MAA Reference Architecture doc<\/a> the current reference evolved (compare both images).<\/p>\n

\"\"<\/a><\/p>\n

Check that with the new reference there is no single point of failure. And as define for required in this architecture, you can upgrade your database to a new version and your application continues to run without interruption. So, we are talking beyond protection, the focus in application continuity at finest allowing to survive to several outages. If you want to check more technical details please read this doc<\/a>. If you look closely you need to have four database failures (complete) to have unavailability. <\/p>\n
