Amazon Cognito User Pools vs Identity Pools

2024-08-29T01:45:49+00:00

Bookmarks Amazon Cognito User Pools Amazon Cognito Identity Pools With the proliferation of smartphones in our connected world, more and more developers are quickly deploying their applications on the cloud. One of the first challenges in developing applications is allowing users to log in and authenticate on your applications. There are multiple stages involved in user verification and most of these are not visible from the end-user. AWS provides an easy solution for this situation. User Identity verification is at the core of Amazon Cognito. It provides solutions for three key areas of user identification:  [...]

AWS Transit Gateway

2024-11-14T08:48:23+00:00

With this service, customers only have to create and manage a single connection from the central gateway into each on-premises data center, remote office, or VPC across your network. If a new VPC is created, it is automatically connected to the Transit Gateway and will also be available to every other network that is also [...]

Backup and Restore vs Pilot Light vs Warm Standby vs Multi-site

You should select the most appropriate DR plan to meet your company RTO and RPO. Consider also your budget and which system elements are most critical for your business. Backup and Restore Pilot Light This DR plan provides the slowest system restoration after a DR event. You take frequent snapshots of your data such as those in Amazon EBS Volumes and Amazon RDS databases, and you store them in a durable and secure storage location such as Amazon S3. There are many ways for you to move data in and out of S3 Transfer over the network via S3 Transfer [...]

Redis Append-Only Files vs Redis Replication

2023-04-10T05:21:12+00:00

Redis Append-Only Files (AOF) Redis Replication You can enable the Redis append-only file feature (AOF) for data durability. It is similar to creating manual backups. When enabled, the node writes all of the commands that change cache data to an append-only file.  When a node is rebooted and the cache engine starts, Redis goes through an AOF to replay the actions that were performed before the crash; the result is a warm Redis cache with all of the data intact. To enable AOF for a cluster running Redis, you must create a parameter group with the appendonly parameter set to [...]

Service Control Policies (SCP) vs IAM Policies

2023-04-12T00:38:41+00:00

Service Control Policies (SCP) IAM Policies SCPs are mainly used along with AWS Organizations organizational units (OUs). SCPs do not replace IAM Policies such that they do not provide actual permissions. To perform an action, you would still need to grant appropriate IAM Policy permissions. Even if a Principal is allowed to perform a certain action (granted through IAM Policies), an attached SCP will override that capability if it enforces a Deny on that action. SCP takes precedence over IAM Policies. SCPs can be applied to the root of an organization or to individual accounts in an OU. When you [...]

S3 Transfer Acceleration vs Direct Connect vs VPN vs Snowball Edge vs Snowmobile

2024-01-18T07:05:33+00:00

S3 Transfer Acceleration (TA) AWS Direct Connect AWS VPN Amazon S3 Transfer Acceleration makes public Internet transfers to S3 faster, as it leverages Amazon CloudFront’s globally distributed AWS Edge Locations. There is no guarantee that you will experience increased transfer speeds. If S3 Transfer Acceleration is not likely to be faster than a regular S3 transfer of the same object to the same destination AWS Region, AWS will not charge for the use of S3 TA for that transfer. This is not the best transfer service to use if transfer disruption is not tolerable. S3 TA provides the same security [...]
