<note tip>Spinakker pros</note> Advantages

• no downtime
• quick rollback
• predicatable release time

<note important>Spinakker cons </note>

Disadvantages

• Cost -2x servers
• databases required extra work
• development time to implement

Blue-Green deployment

• Two identical production environments
• only one serves requests
• deploy to the new one;test;route traffic

Existing setup we cannot run stand alone run one by one node deployment and test
because both nodes are pointing to single memcache instances for Application cache

we have to create two more app servers prodapp05 prodapp06 and one more prodcollab02 server for blue green deployment setup

we can achieve this blue green deployment without spinakker aslo 

need to implement mysql master master setup as well




things to do later we can adopt slowly spinakker
