You can also choose to replicate to other regions to be protected again failure of an entire AWS region – though often data protection laws mean that might not be an option for you if you hold personal data and there is only one AWS region in your country.ĪWS RDS Multi-AZ promises a monthly up-time of 99.5% (which allows for 22 minutes of downtime per month). If the primary AZ goes down, then failover will happen automatically. With this enabled, writes are performed synchronously to a replica in a second availability zone (usually a separate physical data centre in the same region). Instead, HA is achieved using multiple Availability Zones (AZ). In RDS you don’t use Availability Groups, Log Shipping or any of that stuff. Through SSMS you have an access level slightly below Sa – which limits you to only what is allowed. You can still connect to and manage your instance using SSMS, but you have no direct access to the server hosting it, such as configuration of the OS, or access to the disks. This is not intended to be comprehensive and please bear in mind that AWS is a fast-moving beast – changes happen regularly. So, what do you give up and what do you gain? Here’s a quick summary of a few things I’ve noticed. RDS is what’s known as a PaaS offering (Platform as a Service).
#Sql server connection string aws.amazon update#
You can still pick the version of SQL Server you want installed, usually down to which cumulative update you want – though note that RDS normally lags behind the latest box version of SQL by 3 months or so. In return you give up some of the control you would have with your own server or VM. This is more of a managed service where Amazon looks after some aspects of your database server for you. Or you can go with Amazon RDS (Relational Database Service). If you take this option, then SQL Server is exactly the same as it would be if you had it on-prem. This is what’s known as the IaaS option (Infrastructure as a Service). There are also images you can use that will have these pre-installed.
#Sql server connection string aws.amazon install#
One is just to have an EC2 instance (a VM) and install the versions of the OS and SQL Server you want. If you plan on using Amazon Web Services (AWS) to host your SQL Server based applications in the cloud, then you have a couple of options.
