Using two c3.large instances to serve 16,000 requests a day (~11 requests a minute) is akin to using a muscle car to commute a quarter mile - you&#x27;re vastly over-provisioned for such a simple workload.<p>This kind of workload could easily be handled by a pair of t2.micro instances. This would cut your costs for dedicated servers to around $0.40 a day.<p>Plus, you could then take advantage of persistent in-process memory caches and warm services, helping to speed up your responses even further.<p>Using tools like Lambda come with a number of advantages, but you give up a lot of control at the same time. Perhaps this isn&#x27;t a problem for most side projects, but for business critical software I&#x27;d be very leery of handing that much control over to someone as uncommunicative as Amazon.
