Network connectivity is the most fundamental and often ignored component in our daily life and work, we always take it for granted. <\/p>\n\n\n\n
Sometimes our applications require performance, availability and security levels that our normal internet connection doesn\u2019t provide, especially when we want our on-premise running environment to take advantage of cloud services (like cloud storage). <\/p>\n\n\n\n
When a low-latency, constant and predictable connection to cloud resources is required a VPN connection using your internet service provider isn\u2019t the best option, luckily enough there\u2019s a service for that.<\/p>\n\n\n\n
Meet AWS Direct Connect<\/strong>: an AWS service for the creation of dedicated network connections between office, on-premise data centers, or colocations and the AWS Cloud that bypass the Internet entirely, removing unpredictability and network congestion, allowing a more consistent, fast, and low-latency access to Cloud Resources to satisfy business-critical needs. <\/p>\n\n\n\n AWS Direct Connect is a service available at locations all around the world with flexible connection options starting from a 50 Mbps hosted connection to a 100Gbps dedicated connection.<\/p>\n\n\n\n Let\u2019s deep dive into some terminology:<\/p>\n\n\n\n A Direct Connect Location<\/strong> is a physical location where Direct Connect is accessible via a standard cross-connect, so, if the equipment is already in an available location, access to AWS Cloud resources is only a matter of datacenter cabling. For other cases connectivity to a location is made available by selected APN partners that have passed a technical validation for following AWS service best practices. <\/p>\n\n\n\n A Direct Connect Location is physically directly linked with a default AWS Region but any other region is accessible through AWS proprietary network internal routing. A list of available locations and associated regions is available at https:\/\/aws.amazon.com\/directconnect\/locations\/<\/a><\/p>\n\n\n\n An APN Partner<\/strong> can help to establish network circuits between an AWS Direct Connect location and the data center, office, or colocation environment while giving assistance in constructing a hybrid environment.<\/p>\n\n\n\n A Dedicated Connection<\/strong> is a physical Ethernet connection associated with a single customer, with two options for port speed (1 Gbps and 10 Gbps), it gives the ability to define up to 50 virtual network interfaces that behave like a single VLAN with a BGP Peering session on it, you can also attach this virtual interface to a Transit Gateway to implement advanced routing between VPCs<\/p>\n\n\n\n A Hosted Connection<\/strong> has more options for port speed, starting from 50Mbps up to 1Gbps, for use cases that do not require high capacity. With a hosted connection there\u2019s only a single virtual network interface with a BGP Peering session, on a physical link shared with other customers. If additional interfaces are required additional hosted connections have to be provisioned, a Transit Gateway attachment is not available with this type of connection.<\/p>\n\n\n\n Resiliency<\/strong>: even if Direct Connect is a low-latency, constant and predictable connection there\u2019s always the possibility that something goes wrong.
The highest level<\/strong> of resiliency can be achieved using separate connections that terminate on separate devices in more than one location, as shown below<\/p>\n\n\n\n
