Hybrid IT environments
Hybrid IT environments are becoming increasingly common as organizations seek to leverage the benefits of both on-premises and cloud-based infrastructure. AWS offers a range of services that can help organizations to seamlessly integrate on-premises infrastructure with AWS Cloud resources. For example, AWS Direct Connect allows organizations to establish a dedicated network connection between their on-premises data center and AWS, providing a more reliable and secure connection than internet-based connections. Additionally, services such as AWS Storage Gateway can be used to extend on-premises storage to AWS, enabling organizations to take advantage of the scalability and cost-effectiveness of cloud storage.
AWS provides a comprehensive set of services for building, deploying, and managing cloud-based applications. These services include compute, storage, database, and networking services, as well as tools for monitoring, logging, and security. AWS Lambda, for example, allows developers to run code in response to events, without the need to provision or manage servers. AWS Elastic Beanstalk enables developers to deploy and manage applications in multiple languages, including Java, .NET, PHP, Node.js, Python, Ruby, and Go. AWS also offers a range of container services, such as Amazon ECS and Amazon EKS, which can be used to run and manage containerized applications on AWS.
Managed Active Directory services
AWS offers a range of managed Active Directory services, including AWS Directory Service for Microsoft Active Directory, which provides a fully-managed Microsoft Active Directory service in the AWS Cloud. This service enables organizations to use existing Active Directory identities and group policies to manage AWS resources, without the need to deploy and manage their own domain controllers.
