AWS Migration from On-Premise to Cloud

AWS Migration(On-premise to AWS):
---------------
1. Data Movement
2. Migrating Servers
3. Application Migration

Data Movement:
-------------
Example:Sony Games,Mobiles,movies. to S3 glaciers.

Console --> Migration-->Snowball

(for moving heavy data like 100 PB,they provide an empty box to transfer data),physical shipment will be done after import/export.

1 snowball box= 80 TB
1 snowmobile (truck/container) = upto 100PB

Migration Servers:
-------------
AWS Native tool: Server Migration Service (free)

AWS Console--services--migration--server migration service

click on connectors tab -- deploy a connector link.--download OVA file button.

Import this OVA file to the VCenter server.

How to do that?

ESC Vsphere console -->File --> Deploy OVF Template. --> Browse the OVA file.

credentials, can be retrieved using google:aws sms user guide
And see remaining steps from the pdf downloaded.

After up, connect from browser to http://ip of the machine downloaded.

provide region and user details(access key and secret key) to whom we provide servermigrationconnector permission in the IAM of AWS accout.

And also, provide Vcenter details .

After this configuration, this local machine will be shown in the AWS connectors section in our AWS console.

Now,on console, click on Servers and click "Re-Import Server Catalog".IAM role "sms" is selected automatically.

This will display all the machines in the esx server.
Select the machine and click "Create replication job"
Select one-time or "replicate server every"

It will create an AMI, not direct machine.
We can use this AMI to create new machines/instances.

After this process, delete replication jobs and disassociate connectors.

If migrating from a different DB engine, we can use AWS schema conversion tool to generate new schema.

In DB Migration, DMS, Replication Instances , if there, then there will be charges for that.So cross check if any.

AWS Application Discovery service:
---
when we click "start discovery", it will download a client app and it will scan our vcenter architecture and give an overall report which we can use this report in the Migration Hub/Applications
