What is AWS?
Amazon Web Services (AWS) is a global cloud-based product offering of, but not limited to, storage, databases, analytics, networking, mobile, IoT, security, and enterprise applications. AWS has over 200 services available that allows enterprises, start-ups, and small to medium-size business to assess the building tools they need to respond quickly to the constantly evolving requirements of IT.
What is Cloud Migration?
Cloud migration is the process where you move your data and IT resources to the cloud. In the past, organizations ran their applications and IT services in an on-premises data center. Today, cloud providers allow businesses to move their data off-premises, and reduce IT costs while improving performance, but there are security, convenience, and other advantages, too.
