How to Name Tags? Take note of the below while naming IAM roles, IAM users, STS federated user sessions and STS assume-role sessions: Tag keys and values of tags are capable of having spaces, letters, numbers and the following symbols: _ . : / = + – @ . Tag key–value pairs: not case sensitive but preserved so as to not be able to include different Apartment and apartment tag keys. Tag values or tag keys cannot start with the text aws:. (it’s only for internal use). A tag can have empty values like pageNumber= “ ” . Tag keys are not capable of being […]

Roles or Instance Profiles Deletion How to View Role Access? Date of role’s last activity: – May not be as that of the last date reported in Access Advisor tab. – Has the last trial of accessing any service. Only activity of allowed services by role’s permissions policies will be reported using the Access Advisor tab. Viewing when role got last used through console: login to Management Console and head straight to the IAM console using this link https://console.aws.amazon.com/iam/. From navigation pane, click on Roles. Go to the role’s row that you’d like to view, and your results may get narrowed down using the search field. […]

EC2 Scheduled Events What are the different Types of Scheduled Events? Amazon EC2 works with the below listed types of events for your instances, for which the event is occurring at a specifically scheduled time: – Instance stop: The instance gets stopped at a scheduled time. When it is started again, it will be migrated to another new host. Just with instances supported by Amazon EBS. – Instance retirement: The instance gets stopped at the scheduled time, in case it is supported by Amazon EBS, or otherwise terminated in case it is supported by the instance store. – Instance reboot: […]

EC2 Instances: Status Checks Status checks will get performed each and every minute, while returning a status of either a pass or a fail. In case every single one of the checks pass, the final status of the instance is going to be OK. In case 1 or more checks tend to fail, the final status will be impaired. Status checks will be built into Amazon EC2, which means that they are not capable of being disabled or deleted. The moment a status check fails, the associated CloudWatch metric for status checks will get incremented. You get the chance to […]

EC2 Instances: Status Check Alarms How to Create and Edit Status Check Alarms? It is possible to utilize the status check metrics for creating CloudWatch alarms in order to notify you when an instance gets a failed status check. Create a Status Check Alarm through the Console Follow the below process for the sake of configuring an alarm that will send you a notification through your email, or stop, terminate, or even recover an instance whenever it fails in a status check. How to create a status check alarm using the console? Go to the Amazon EC2 console through this […]

Types of EC2 Placement Groups Upon launching new EC2 instances, the service tends to add the instance so that every one of your instances get spread out over underlying hardware in order to get the lowest possible correlated number of failures. Placement Groups are used for the sake of influencing the placement interdependent groups of instances so that they supply the requirements of your workload. According to which type of workload you possess; you may get to create a placement group through utilizing a chosen placement strategy out of the following ones: Cluster: works by packing instances close to each […]

EC2 Placement Groups: Rules and Limitations General Rules: Prior to using placement groups, you must know the below rules: Name of placement groups: unique within the account for each Region. Placement groups cannot be merged. Instance: launched in 1 placement group at a time, and it’s not possible to span various placement groups. On-Demand Capacity Reservation + zonal Reserved Instances offer a capacity reservation for instances in one Availability Zone. This may be utilized by instances in a placement group. (cannot explicitly reserve capacity for a placement group). Instances having a tenancy of host may not possibly get launched in […]

Launch Instance Wizard: How to Launch AWS Instance An instance may be launched through the launch instance wizard. This wizard sets out every launch parameter needed for the launching of a chosen instance. Wherever a default value is set by the wizard, it can be accepted or changed to a specific value of your own. An AMI + a key pair must be chosen for launching the instance. Prior to launching an instance, you must be set up. Note Upon launching an instance outside of Free Tier, you will get charged for the period in which instance continues to run, […]

EC2 Launch Instance Wizard: Adding and Configuring Instance Options on AWS Adding Storage AMI: has multiple volumes of storage (root device volume). From the Add Storage page, set more volumes for attaching to the instance through selecting Add New Volume. You may start configuring every volume as needed, and select Next: Add Tags. – Type: Choose instance store or EBS volumes to get them associated with an instance. The instance chosen is what affects the types of volume found in the list. – Device: Choose one found in the list of device names for the required volume. – Snapshot: Fill […]

EC2 CPU Options CPU options may be specified while instance launch is occurring. The below listed examples are for r4.4xlarge instance, which includes default values as follows: CPU cores: 8 (DEFAULT) Threads per core: 2 (DEFAULT) vCPUs: 16 (8 * 2) (DEFAULT) Number of CPU cores: 1, 2, 3, 4, 5, 6, 7, 8 (VALID) Number of threads per core: 1, 2 (VALID) Multithreading DISABLED For disabling multithreading, you need to specify 1 thread per core. Disabling multithreading – instance launch (console) Go through “Launching an Instance Using the Launch Instance Wizard” process. From the Configure Instance Detailspage, under CPU options, select Specify CPU options. Under Core […]

How to Optimize EC2 CPU Options? – Overview EC2 instances are utilized for the support of multithreading, which is the enabling of various threads to start running simultaneously on just one CPU core. Every thread gets shown as a vCPU on the instance. Every instance includes a default number of CPU cores that changes in parallel with the instance’s type. As an example: m5.xlarge instance contains 2 CPU cores + 2 threads/core by default (4 vCPUs). Important: Every vCPU = a thread of a CPU core (excluding T2 instances) Normally, an EC2 instance type is found, which contains a mixture of […]
