We delete files all the time.
The cloud may feel abstract, but behind it are real machines storing real physical data.
When you delete a file, cloud providers don’t simply press a magical erase button.
Instead, they use a combination of:
>> software, >> encryption, >> storage management, >> and sometimes even physical destruction
to ensure your data is eventually gone for good.
So the next time you click “Delete,” remember.

If you want to install Microsoft Exchange Server 2019, there is one thing you should never skip: the prerequisites.
Many beginners try to install Exchange directly and then get errors. The setup fails, or things break later. This happens because Exchange depends on many system components working correctly before installation.
Think of it like building a house. If the base is weak, the whole house will have problems. Similarly, Exchange Server needs a strong foundation.
In this article, we will prepare that foundation step by step in a simple way.

Benefits of Moving from On-Premises Microsoft Exchange to AWS-hosted Exchange
If your company is still using Microsoft Exchange on local servers (on-premises), you might be thinking about moving it to the cloud.
One popular option is AWS (Amazon Web Services).
In this guide, we will explain everything in simple words so anyone can understand what it means and why it’s useful.
What “Exchange on AWS” typically means
AWS does not offer a native “AWS Exchange” service; instead, customers run Microsoft Exchange Server on EC2 instances, usually as part of a hybrid Active Directory environment extended into AWS or integrated with AWS Managed Microsoft AD Hybrid Edition.
In this model, Exchange roles (Client Access and Mailbox servers for supported versions) run on Windows Server in AWS, while AWS provides compute, storage, networking, and supporting services such as Route 53, Direct Connect, and security tooling.
Cost optimization compared with on‑premises
Independent economic validation from TechTarget ESG found that migrating workloads from traditional on‑premises infrastructure to AWS can reduce compute costs by about 63 percent, networking costs by about 66 percent, and storage costs by about 69 percent over three years, primarily through elastic scaling and managed services.
These savings patterns apply to Exchange as well because EC2, EBS, and AWS networking replace physical servers, SANs, and network gear that previously had to be purchased and maintained up front.
AWS licensing options such as Amazon EC2 Dedicated Hosts with AWS License Manager allow organizations to bring existing Microsoft Exchange and Windows Server licenses, helping further reduce costs while maintaining a highly available design.
Elastic scalability and flexibility
On-premises Exchange deployments typically require over‑provisioning hardware to handle peak loads or future mailbox growth, which leads to idle capacity most of the time.
By contrast, Exchange on AWS runs on EC2, so organizations can change instance sizes, add or remove servers, and scale storage capacity much more quickly as mailbox counts or usage patterns change.
This elasticity is especially useful during mergers, seasonal peaks, or migration waves, because additional Exchange servers can be spun up temporarily in AWS and removed once the demand subsides.
High availability and disaster recovery
Exchange’s native high‑availability features, such as Database Availability Groups (DAGs), can be combined with AWS’s multi‑Availability Zone (AZ) infrastructure to achieve robust resilience without building multiple physical data centers.
Reference architectures from AWS deploy Exchange mailbox servers and domain controllers across separate AZs, so that a single‑site failure does not take down the entire messaging service.
More broadly, AWS reports that customers migrating from on‑premises infrastructure achieve up to a 69 percent reduction in unplanned downtime, reflecting the operational resilience benefits of running workloads like Exchange on cloud infrastructure.
Performance and global reach
Running Exchange on AWS allows organizations to place mailbox servers in regions closer to end users, reducing latency compared with routing all traffic back to a central on‑premises data center.
Real‑world AWS customers such as Snap have cited lower latency and better responsiveness for end‑user communication workloads after moving from a centralized data center model to AWS regions located near users.
For globally distributed organizations, Exchange on AWS can be paired with services such as AWS Direct Connect and VPN to create hybrid connectivity that keeps local access fast while still integrating with existing on‑premises systems.
Security, compliance, and identity integration
Deploying Exchange on AWS runs inside Amazon Virtual Private Cloud (VPC) environments, benefiting from network isolation, security groups, and integration with AWS security services such as CloudWatch, CloudTrail, and Security Hub for monitoring and auditing.
AWS’s Migration Acceleration Program emphasizes that customers moving to AWS strengthen security and availability, and many organizations leverage AWS’s compliance programs to help meet regulatory requirements while still maintaining control of their Exchange data and configuration.
Exchange on AWS can integrate directly with extended on‑premises Active Directory or AWS Managed Microsoft AD Hybrid Edition, preserving existing identity, authentication, and schema extensions while shifting the infrastructure to AWS.
Operational efficiency and modernization
Running Exchange in AWS eliminates the need to maintain physical servers, storage arrays, and facilities, allowing operations teams to focus on patching, backup, and configuration at the OS and application layers rather than hardware lifecycle tasks.
AWS Managed Microsoft AD Hybrid Edition and related patterns simplify extending or hosting Active Directory in AWS, which in turn streamlines management of Exchange and other Windows workloads in the cloud. Organizations can also integrate Exchange with AWS services such as Amazon S3 and Amazon S3 Glacier for cost‑effective backup or archiving, and use observability tools like Amazon CloudWatch to monitor performance and automate alerting.
Typical use cases
Common scenarios for moving from on‑premises Exchange to AWS include data center exit or consolidation, where Exchange is one of several Windows workloads being re‑hosted to reduce real‑estate and hardware costs.
Another frequent use case is version upgrades: organizations use AWS to deploy a newer Exchange version in the cloud and then migrate mailboxes from legacy on‑premises servers, avoiding a large hardware refresh. Some organizations also choose Exchange on AWS as an intermediate step in a longer‑term roadmap toward Microsoft 365, using AWS to provide a stable, scalable platform while planning or piloting a move to hosted Exchange Online.
Trade‑offs and considerations
Despite these benefits, Exchange on AWS remains a self‑managed deployment: IT teams are still responsible for Exchange patching, backups, capacity planning, and troubleshooting, unlike fully managed services such as Microsoft 365.
There are also cases where staying on‑premises or moving directly to Exchange Online may be more appropriate, for example when organizations have already invested heavily in their own data centers or want to offload application management entirely.
A careful assessment of mailbox counts, compliance needs, latency requirements, existing investments, and long‑term collaboration strategy is therefore essential before deciding whether Exchange on AWS is the right migration target.
