What Is the
Snow Family?
The Snow Family is a set of secure appliances that provide petabyte-scale data collection and processing solutions at the edge and migrate
large-scale data into and out of AWS. They offer built-in computing capabilities, enabling customers to run their operations in remote
locations that do not have data center access or reliable network connectivity.
Not being able to transfer over the internet, having a large amount of data,
or having a very slow internet connection could all be reasons to use Snowball.
The Snow Family works to get data into AWS, as well as shipped back to you.
What is Snowcone?
THE SMALLEST DEVICE IN THE SNOW FAMILY

What is Snowmobile?
THE HEAVY HITTER
- 100 PB of storage

- Did we say it’s cool?
- There’s a good chance you don’t need this
What Is Storage
Gateway?
Storage Gateway is a hybrid cloud storage service that helps you merge on-premises resources with the cloud. It can help with a one-time migration or a long-term pairing of your architecture with AWS.
What is File Gateway?
File gateway bridges local file storage over NFS and SMB with S3 Storage.
It supports multi site, maintains storage structure, integrates with other AWS products and supports S3 object lifecycle Management.
- NFS or SMB mount
- NotifyWhenUploaded: Sends you notification through CloudWatch Events when all files written to your file share have been uploaded to Amazon S3(because the file is not seen uatimatically, without a file listing, when a file is added on S3).
What is Volume Gateway?
Storage gateway is a product which integrates local infrastructure and AWS storage such as S3, EBS Snapshots and Glacier. Uses iSCSI mount. The communication happens through the public internet or Direct Connect.
Stored mode:
- Does not improve Datacenter capacity. The main copy of the data is stored on the Storeage Gateway VM on premeses, and create EBS snaphots through the public Storage Gateway endpoint on AWS.
- Perfect for backup and DR.
- Low latency access to data
Cached mode:
- The primary location for the data is in S3. The Storage Gateway VM instead of a local storage volume has a local cache.
- Data center extension architecture. Perfect for gradually migration.
What is Tape Gateway?
DITCH THE TAPES Virtual Tape Libray (VTL)
- Replace physical tapes
- Doesn’t change current workflow
- Encrypted communication
- iSCSI
What Is
DataSync?
AWS DataSync is an agent-based solution for migrating on-premises storage to AWS. It allows you to easily move data between NFS and SMB shares and AWS storage solutions.
for a one-time migration. 10Gbps per agent
If you have hybrid architecture and want a continuous sync, think Storage Gateway.
- keeps metadata(timestamps, permissions).
- Built in data validation. and Automatic recovery from transit errors.
- AWS service integration(fx to EFS, to S3)
- pay as you use.
- suppot schedules
What Is the AWS
Transfer Family?
The AWS Transfer Family allows you to easily move files in and out of S3 or EFS using Secure File Transfer Protocol (SFTP), File Transfer Protocol over SSL (FTPS), or the File Transfer Protocol (FTP), AS2(Applicability Statment 2) for B2B.
The AWS Transfer Family excels when you have a collection of leagacy
applications using protocols that cannot be changed. You can easily “trick”these applications into using S3 storage.. The DNS entry stays the same, but the location for the storage becomes S3.
- The endpoint can be public(SFTP), in vpc internet(AS2, SFTP,FTPS), in vpc internal(AS2, SFTP,FTPS, FTP).
What Is AWS
Migration Hub?
AWS Migration Hub gives you a single place to track the progress of your application migration to AWS. It integrates with Server Migration Service (SMS) and Database Migration Service (DMS).
For application migration(database or server). complete migration. It’s easy to migrate to Aurora or RDS.
What AWS Application Discovery Service can do?
- Plan: Helps plan migrations to AWS via collection of usage and configuration data from on-premises servers
- Simplify: Integrates with AWS Migration Hub, simplifying migrations and tracking migration statuses
- Track: Helps you easily view discovered servers, group them by application, and track each application migration
What is AWS Application Discovery Service
two types of discoveries.
Agentless:
- Completed via the Agentless Collector
- OVA file within the VMware vCenter
- Identifies hosts and VMs in vCenter
- IP and MAC address, resource allocations, and hostnames
- Utilization of data metrics
Agent Based:
- Deploy AWS Application Discovery Agent
- Each VM and each physical server
- Installer for Windows and Linux
- Static config data, time-series performance info, network connections,
and OS processes
What is AWS MGN?
AWS Application Migration Service
- Automated lift-and-shift service for expediting migration of apps to AWS
- Used for physical, virtual, or cloud servers to avoid cutover windows or
disruptions - Replicates source servers into AWS, and automatically converts and launches on AWS to migrate quickly
for infrastructure
What are RTO and RPO in AWS MGN?
- Recovery Time Objective: Typically just minutes, dependent on OS boot time
- Recovery Point Objective: Measured in the sub-second range
What Is AWS DMS?
AWS DATABASE MIGRATION SERVICE
- It allows for easy migration of relational databases, data warehouses, NoSQL databases, and other data stores.
- Migrate data between AWS and on-premises — either into or out of AWS.
- You have the option to perform a one-time migration or continuously
replicate ongoing changes - The SCT allows for translating database schemas to new platforms.
- Since it is a cloud service, you gain the advantages of AWS cost, efficiency, security, and more.
One of the endpoints must be within AWS.
What is AWS SCT?
AWS Schema Conversion Tool (SCT)
- Leverage the SCT to convert existing database schemas from one engine to another.
- Convert many types of relational databases, including both OLAP and OLTP. It even supports data warehouses.
- Converted schemas can be used for any supported Amazon RDS engine type, Amazon Aurora, or Amazon Redshift.
- You can even use the converted schemas with databases running on EC2 or data stored in S3.
What are the three different migration types?
- Full Load: All existing data is moved from sources to targets in
parallel. - Full Load and Change Data Capture (CDC): Full load plus CDC
captures changes to source tables during migration. - CDC Only: Only replicate the data changes from the source database.
What is AWS SMS?
AWS Server Migration Service
SMS is perfect for scenarios like simplifying migrations of critical
VMs from on-premises, easily migrating VMs from other cloud
providers, and minimizing downtimes during cutovers.
What is BGP (Border Gateway Protocol)?
BGP is an internet protocol used for routing between autonomous systems (ASes). It plays a key role in global internet routing, helping routers make decisions on the best path for data packets. BGP uses attributes like AS path and next-hop to make routing decisions and is critical for internet stability and efficient data transfer. It’s used by ISPs, large enterprises, and organizations to manage network traffic and ensure reliable internet connectivity.
