EC2, also known as Elastic Compute Cloud, is a service launched by Amazon Web Services (AWS) that offers users the ability to lease virtual machines (VMs) across multiple regions. It liberates businesses from the constraints of physical hardware and enables them to scale computing resources with unparalleled programmable flexibility. EC2 is a vital component of the cloud computing landscape, providing organizations with the capability to adapt to changing demands, provision and deprovision VMs on-demand, optimize performance, and achieve potential cost efficiency using its hybrid pay-as-you-go and reservation pricing model. As an integral part of the AWS ecosystem, EC2 seamlessly integrates with other AWS services, offering a wide range of possibilities in virtual networking. It provides primitives to establish secure virtual networks, manage traffic flows, and interconnect various applications and resources within the cloud environment. With EC2, businesses can architect sophisticated infrastructures tailored to their software needs, fostering enhanced connectivity and seamless data exchange.
