Customer Master Key (CMK) Policy Management in AWS KMS

2023-06-07T04:11:41+00:00

What is a Customer Master Key (CMK)? In security, a master key is what you use to encrypt all other encryption keys in your system. Customer master keys are logical representations of a master key. They are the primary resources in AWS KMS. The CMK contains the key material used to encrypt and decrypt data. It also contains metadata such as the key ID, creation date, description, and key state. You can start using AWS KMS through the web console or via API. There are two types of CMKs that you can create in AWS KMS: symmetric CMK and asymmetric [...]

The New Tutorials Dojo Practice Test Portal is now LIVE!

2023-06-07T07:01:16+00:00

The New Tutorials Dojo Practice Test Portal is now LIVE! For the past two years of offering practice test courses on Udemy, we have gathered tons of feedback on how to improve our students’ learning experience. One of the most commonly requested feature is the ability to view the answers as you go through each question. A lot of you are able to learn better with this mode vs. having to wait to finish the entire set before being able to see the answer key. It is therefore with absolute delight that we announce the availability of this feature plus [...]

Latency Routing vs Geoproximity Routing vs Geolocation Routing

2023-04-10T03:27:57+00:00

  Latency Routing Geoproximity Routing Geolocation Routing Definition Lets Route 53 serve user requests from the AWS Region that provides the lowest latency. It does not, however, guarantee that users in the same geographic region will be served from the same location. Latency-based routing is based on latency measurements performed over a period of time, and the measurements reflect changes in network connectivity and routing. Lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources.  You can also optionally choose to route more traffic or less to a given resource [...]

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

2023-04-10T06:17:02+00:00

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 [...]

Elastic Beanstalk vs CloudFormation vs OpsWorks vs CodeDeploy

2023-04-08T05:52:39+00:00

AWS Elastic Beanstalk AWS CloudFormation AWS Elastic Beanstalk makes it even easier for developers to quickly deploy and manage applications in the AWS Cloud. Developers simply upload their application, and Elastic Beanstalk automatically handles the deployment details of capacity provisioning, load balancing, auto-scaling, and application health monitoring. This platform-as-a-service solution is typically for those who want to deploy and manage their applications within minutes in the AWS Cloud without worrying about the underlying infrastructure.  AWS Elastic Beanstalk supports the following languages and development stacks: Apache Tomcat for Java applications Apache HTTP Server for PHP applications Apache HTTP Server for Python [...]
