+- Benefits
+	- simplifies and automates HA
+		- EKS control planes are [multi AZ by default](https://docs.aws.amazon.com/eks/latest/userguide/disaster-recovery-resiliency.html)
+		- self healing
+		- requires no developer interaction
+	- can still use managed services
+		- rds
+		- redis
+			- can deploy a second redis for event streaming if redpanda not suitable
+	- reduces number of AWS accounts
+		- cost savings, see below
+	- cloud agnostic
+	- security improvements
+		- no need for devs to SSH into machines to debug
+	- flux for gitops
+	- allows for easy deployments of new OEMs 
+	- maintains single tenancy with namespaces
+
+- Cost
+	- Last Month's Bill:
+		### PROD
+		**Total USD 1,079.60**
+		$0.0146/hr t2.micro USD 10.51
+		$0.20/hr c5a.xlarge USD 144.00 
+		c5a.xlarge Compute Savings Plans USD 144.00
+		$0.80/hr c5a.4xlarge USD 576.00
+		$1.60/hr c5a.8xlarge Instance Hour 1,440 Hrs	USD 2,304.00
+		c5a.8xlarge Compute Savings Plans 1,131.817 Hrs
+		
+		### DANDIS
+		**Total USD 1,020.67**
+		$0.0238 per t3a.small USD 51.38
+		$0.0475 per t3a.medium USD 34.15
+		$0.0695 per r6gd.medium USD 50.04
+		$0.20 per c5a.xlarge USD 431.60
+		c5a.xlarge Compute Savings Plans USD 431.60
+		$0.432 per m6a.2xlarge USD 311.04
+		$0.80 per c5a.4xlarge USD 575.20

+	- [EC2 Cost Estimate](https://calculator.aws/#/estimate?%20id=0180036d04e86d221898455f124054dc18922ca5&id=883b6de14b680f78f87f3fffd07b1b99455abd73)
+	- utilises servers more
+		- DANDIS m6a.2xlarge running at ~10% cpu usually
+		- autoscaling
+		- fargate possible but annoying
+	- EKS
+		- dev + prod all we need
+		- flat $0.10/hr per cluster
+			- 2 Clusters x 0.10 USD per hour x 730 hours per month = 146.00 USD
+			- less than a single c5a.xlarge 
+				3 of which in DANDIS account doing nothing
+		- In prod instances max 27% cpu across the last week
