Pre-requisite: Amazon Web Services
AWS ExpressLink is a service provided by Amazon Web Services (AWS) that allows customers to establish a dedicated and private connection between their on-premises data centers and the AWS cloud. This connection is established over a dedicated, leased line, such as a dark fiber or wavelength service. It allows for low-latency, high-bandwidth communication between the customer’s data center and AWS. This service can be used to improve performance for workloads that require high-bandwidth or low-latency connectivity, such as big data and analytics, video streaming, and financial trading applications. ExpressLink can be used in conjunction with other AWS services, such as Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3), to create a hybrid cloud solution.
The key benefit of ExpressLink is the ability to improve performance for workloads that require high-bandwidth or low-latency connectivity, such as big data and analytics, video streaming, and financial trading applications. This is achieved by having a direct and private connection between the on-premises data center and the AWS cloud, which bypasses the public internet, resulting in faster and more reliable data transfer.
AWS ExpressLink also provides a higher level of security and compliance, as the data is transferred over a dedicated connection which is not shared with other customers, and the data is not traversing the public internet, this makes it a more secure way of data transfer.
ExpressLink can be used in conjunction with other AWS services, such as Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3), to create a hybrid cloud solution. This allows customers to easily move data and workloads between their on-premises data center and the AWS cloud, and take advantage of the scalability and flexibility of the public cloud, while also maintaining control and security of their data and applications in their own on-premises data center.
Features of AWS ExpressLink
Amazon Web Services (AWS) ExpressLink is a high-speed, dedicated network connection service that enables customers to directly connect their on-premises infrastructure to AWS. Here are some key features of AWS ExpressLink:
