+# High Availability on AWS
+
+We'll assume you have an AWS account setup already and you're able to 
+login to the AWS console. If you don't have access to some services make 
+sure your AMI user has enough privileges.   
+ 
+Login to your AWS account through the `My Account` dropdown on 
+`https://aws.amazon.com` or through the URI assigned to your team such as
+`https://myteam.signin.aws.amazon.com/console/`. You'll start on the 
+Amazon Web Services console from where we can choose all of the services 
+we'll be using to configure our cloud infrastructure. 
+
+## Database with RDS 
+
+Select the RDS service from the Database section and create a new 
+PostgreSQL instance. After choosing between a Production or 
+Development instance we'll start with the actual configuration. On the 
+image bellow we have the settings for this article but note the 
+following two options which are of particular interest for HA:
+
+1. Multi-AZ-Deployment is recommended as redundancy. Read more at
+[High Availability (Multi-AZ)](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.MultiAZ.html)
+1. While we chose a General Purpose (SSD) for this article a Provisioned 
+IOPS (SSD) is best suited for HA. Read more about it at 
+[Storage for Amazon RDS](http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html)
+
+![RDS Instance Specs](/images/high-availability/instance_specs.png)
+
+The rest of the setting on this page request a DB identifier, username 
+and a master password. We've chosen to use `gitlab-ha`, `gitlab` and a 
+very secure password respectively. Keep these in hand for later.

+
+
+Finally connect to your new RDS instance to verify access and to install 
+a required extension. We can find the host or endpoint by selecting the 
+instance and  we just created and after the details drop down we'll find 
+it labeled as 'Endpoint'; do remember not to include the colon and port 
+number.
+
+
+    psql -U 'gitlab' -d 'gitlabhq_production' -h '<endpoint-no-port>' 
+    psql (9.4.7)
+    Type "help" for help.
+    
+    gitlab=# CREATE EXTENSION pg_trgm;
+    gitlab=# \q
+

+
+## ElastiCache with Redis
+
+Let's choose the ElastiCache service in the Database section from our 
+AWS console. Press the Launch a Cache Cluster and choose Redis for our 
+DB engine.
