Projecting Membership ●Physical 3-tier deployments ●May not allow web server to connect directly to Sql tier ●“Atlas” and smart clients ●Clients can only communicate over Http ●Need app services to work across the Internet ●Physical 3-tier deployments ●May not allow web server to connect directly to Sql tier ●“Atlas” and smart clients ●Clients can only communicate over Http ●Need app services to work across the Internet
