  Consule —————- 1) Traditional methods do not resolve the app's name . in this method, load balancer can resolve, but it is in round-robin fission. if we did any modification it won't update the dynamical but console having an extra feature where there is a Registry that manages all the app info and availability details. 2)Discovery and service configuration tools 3)Container Pilot should use consul for service management Nomad ========== 1)for control deployment and scheduler .hcl format. Service management tool Nomad should be used for managing the containers on one or more servers/clusters. Vault ========= Tool for securely accessing and storing secrets The new component of AN could make use of the latest technology offer by Cobalt to manage the secret AN is only planned for development hence it should not adopt this technology as it will not be accessible in production. cypherstore–is the authorization used by mon servers. What is OAuth? Oauth-token base authentication TTL...

  EC2 (Elastic compute cloud) part-1 ====================================== Amazon EC2 provides scalable computing capacity in the AWS cloud. —> you can use Amazon EC2to launch as many or as few virtual servers as you need, configure security and networking and manage storage —> Amazon EC2 enables you to scale up or scale down the instance —> Amazon EC2 is having two storage options I.e EBS and instance store. —>Pre configured templates are available know as Amazon machine image —>By default, when you create an ec2 account with Amazon, your account is limited to a max of 20 instances per EC2 region, with 2 default High I/O instances. TYPES of EC2 Instances: ——————————————— General-purpose:- Balanced memory and CPU Compute Optimised:- More CPU, than RAM Memory Optimised:- More RAM Storage Optimised:-Low latency Accelerated Computing:- Graphics optimized High memory:-High RAM Nitro System Previous Generation:- EC2 (Elastic compute cloud) part-2 ========================...

  Simple Storage Service S3 (Object level storage any type of data, you can access it anywhere)         2.Elastic file system EFS: (common storage you can share across different regions and VPCs ex: patch files, updated files, Linux files)      3.Elastic block storage EBS (it is accessible through EC2 only like HDD work in a computer)      4.Glacier (): now it is part of S3 storage and cost-effective,     not frequently used data. Snowball :     (Huge amount of data We can transfer one DC to another DC) Part-2 ———————— Block Level v/s Object Lebel Storage: Block storage: —> Block starts is suitable for transactional databases, random read/write loads, and structured database storage —>Block storage divides the data to be stored in evenly sized blocks(data chunks) for instance,       a file can be split into evenly sized blocks before it is stored —>data blocks stored in block storage ...
