What is a X forwarded for header? Identify the originating IP address of a client through a load balancer. If you need the IPV four address of your end, user, look for the X forwarded for header. What is an OSI model A conceptual framework which describes the functions of a network. Beginning with the Application layer which directly serves the end, user, down to physical layer. What the end user sees HTTP, web browsers. Different layers of the model are as follows. Presentation layer Data is in a usable format, encryption, SSH. Session Layer Maintains connections and sessions. Transport layer Transmits data using TCP and UDP. Network layer Logically routs packets based on IP address. Data Link layer Physically transmits data based on MAC addresses. Physical layer Transmits bits and bytes over physical devices. What is the difference between IOPS and throughput? IOPS Measures the number of read and write operations per second. Important metrics for Quick transactions, low latency apps,

Your company has built-in internal scrum tool for Running  all your scrum ceremonies. Usages predictably high between 9-10AM Monday-Friday and also 1 PM-2 PM Thursday and Friday. Which feature of autoscaling will easily repair your system To handle the Load? Target tracking could to work but we need to invest time in determining correct metric to track example (CPU, memory, load balancer requests). Also Manuel Scaling requires that someone changes configuration to scale up and scale down every day.  Finally over provisioning in order to cope with peak demand defeats the purpose of Elastic Scaling of Our compute. For situations where your traffic is very predictable, the easiest way to scale with demand is to create scheduled Scaling Actions. A product manager vox into your office and advises that this simple single node MySQL RDS Instance that has been used for a pilot needs to be upgraded for production. She also advises that they may need to alter the size of The instance once they s

Following points can be considered while creating a highly available architecture depending on scenarios  A spread Placement group Supports a maximum of seven running Instances per availability zone.for example, In A region with three Availability zones, you can run total of 21 instances in the group.If you try to start an eighth Instance in the same availability zone and in the same spread placement group, the Instance will not launch.If you need to have more than seven instances in an availability zone,Then the Recommendation is to use multiple spread Placement Groups. Using multiple spread Placement Groups does not provide guarantee about the spread of instance between groups, but it does ensure the spread for each group, thus limiting impact from certain classes of failures. Durability refers to the ongoing existence of the object or resource. Note that it does not mean you can access it, only that it continues to exist. Groups, Scaling options, configuration templates are componen
