Architecting For Scale : high availability for your growing applications PDF description
Amazon manages the network ACL throughout the life of the instance (they call them security groups). You can change the security group ACLs at any time. If you block access to a port, that port is blocked immediately. If you allow access to a port or IP address, that port or IP address is allowed access immediately. This all happens at the network layer, before the traffic reaches the server for inbound ACL, and after the traffic leaves the server for outbound ACL. No access to software on the server itself is required.
Every day, companies struggle to scale critical applications. As traffic volume and data demands increase, these applications become more complicated and brittle, exposing risks and compromising availability. With the popularity of software as a service, scaling has never been more important.
Updated with an expanded focus on modern architecture paradigms such as microservices and cloud computing, this practical guide provides techniques for building systems that can handle huge quantities of traffic, data, and demand—without affecting the quality your customers expect. Architects, managers, and directors in engineering and operations organizations will learn how to build applications at scale that run more smoothly and reliably to meet the needs of customers.
