最大限度地减少停机时间（Azure网站+ SQL DB）

Question

My Azure websites are down a lot, four outages (30 minutes - 3 hours) in the past 30 days. I only use one small standard website and one web SQL DB in US West so I can't expect 99.5%. This week (a few days ago and currently), 503 errors were / are the problem, but I also experienced substantial DB downtimes at other occasions.

My question is: what can I do (with hopefully not too much additional costs and effort) to raise stability? Which measures did other Azure users try? Would this have prevented the 3 hour downtime last Monday?

Answer 1

There are (at least) three things you can do:

1. Scale your website so that you have 2 instances running ( How to Scale Websites );
2. Deploy a another copy of the website in a different region, and use traffic manager to Load Balance them ( Traffic Manager Overview )
3. Create another instance of the database, and sync them ( Getting Started with Azure SQL Data Sync )

Answer 2

I'd like to point out that with Websites, you get a 99.9% availability for websites running is Basic and Standard mode regardless of the number of instances deployed . You can view the SLA document here: http://go.microsoft.com/fwlink/?linkid=301329&clcid=0x409

Regarding the 503 errors you experiences, this was an intermittent issue http://azure.microsoft.com/en-us/status/#history
