Does Amazon EC2 provides the ability to place instances in multiple locations?
Amazon EC2 is hosted in multiple locations worldwide. These locations are composed of AWS Regions and Availability Zones. Each region is a separate geographic area with multiple, isolated locations known as Availability Zones. Amazon EC2 provides the ability to place instances and data in these multiple locations.
What is the maximum number of instances that you can have running at one time on EC2?
20 instances
Answer. By default, when you create an EC2 account with Amazon, your account is limited to a maximum of 20 instances per EC2 region with two default High I/O Instances (hi1.
Which features ensures even distribution of traffic to Amazon EC2 instances in multiple availability zones registered with a load balancer?
Elastic Load Balancer allows the incoming traffic to be distributed automatically across multiple healthy EC2 instances.
Can a reserved instance can be moved from one region to another?
We can not move the standard reserved Instances from one region to another. But It is possible with convertible reserved instances.
Are the Reserved Instances available for Multi AZ deployments?
Amazon RDS manages the work involved in setting up a relational database: from provisioning the infrastructure capacity you request to installing the database software. With optional Multi-AZ deployments, Amazon RDS also manages synchronous data replication across Availability Zones with automatic failover.
How many EC2 instances does Amazon have?
With EBS, it is possible to increase or decrease the amount of storage available to an EC2 instance and attach EBS volumes to more than one instance at the same time. Elastic IP addresses. Amazon’s Elastic IP service lets IP addresses be associated with an instance.
How do I increase my EIP?
To request an increase using the Amazon EC2 console Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/ . From the navigation bar, select a Region. From the navigation pane, choose Limits. Select the resource in the list, and choose Request limit increase.
Can EC2 instances communicate with each other?
To communicate with the other EC2 instance you would use a network protocol over TCP/IP. To do that you would need to get the Security Groups and nACLs set correctly to allow the traffic. That would allow you to (for example) Ping the other EC2 instance.
Can EC2 instances in the same VPC talk to each other?
Can Amazon EC2 instances within a VPC in one region communicate with Amazon EC2 instances within a VPC in another region? Yes. Instances in one region can communicate with each other using Inter-Region VPC Peering, public IP addresses, NAT gateway, NAT instances, VPN Connections or Direct Connect connections.
What does Amazon Route 53 provide?
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost effective way to route end users to Internet applications by translating names like www.example.com into the numeric IP addresses like 192.0.
What are Amazon EC2 regions and availability zones?
Amazon EC2 is hosted in multiple locations world-wide. These locations are composed of Regions and Availability Zones. Each Region is a separate geographic area. Each Region has multiple, isolated locations known as Availability Zones.
How do I move an EC2 instance to another AWS instance?
To move an EC2 instance: Create a new Amazon Machine Image (AMI) from the source instance. Use the AMI to launch a new instance. Reassign the Elastic IP address from the instance you are moving to the new image.
Can I use Amazon EBS with multiple Availability Zones?
As mentioned earlier, Amazon EBS only replicates within servers on a single Availability Zone and if you were to provide redundancy at the storage level by only using Amazon EBS, you would need to take Amazon S3 snapshots and transfer them over to a different Availability Zone, which has also an additional cost.
What is Amazon EC2 auto scaling and how does it work?
Amazon EC2 Auto Scaling always launches new instances such that they are balanced between zones as evenly as possible across the entire fleet. What’s more, Amazon EC2 Auto Scaling only launches into Availability Zones in which there is available capacity for the requested instance type.
