What is EC2?
EC2 stands for Elastic Compute Cloud and is a web service provided by Amazon Web Service (AWS) that helps in provisioning resizable compute capacity on cloud.
What are the benefits of using EC2?
EC2 helps in scalability, flexibility, cost reduction, reliability, and security in cloud computing.
What are EC2 instances?
EC2 instances are virtual servers that run on Amazon's Elastic Compute Cloud (EC2) and are resizable according to the user's requirements.
What is an AMI?
AMI stands for Amazon Machine Image and it is a pre-configured virtual machine image, which is used to create EC2 instances.
What is an instance type?
Instance type is a way to specify the hardware of the EC2 instance, such as CPU, memory, storage, and networking capacity.
What are reserved instances?
Reserved instances are EC2 instances that are purchased for a period of time and offer significant discounts over on-demand instances.
What is the difference between on-demand and spot instances?
On-demand instances are rented on an hourly or a per-second basis, while spot instances are rented on an auction basis where users bid for computing capacity.
What are security groups in EC2?
Security groups in EC2 are virtual firewalls that allow or deny traffic to and from the instances based on rules that the user defines.
What is an Elastic IP?
Elastic IP is a static, public IPv4 address that can be associated with an EC2 instance and can be remapped to another instance if needed.
What is load balancing in EC2?
Load balancing in EC2 is a way to distribute traffic between multiple instances to improve performance, availability, and fault tolerance.
What is auto scaling?
Auto scaling is a way to automatically adjust the number of EC2 instances based on the demand to maintain performance and cost efficiency.
What is placement groups in EC2?
Placement groups in EC2 are logical groupings of instances that are placed together in order to achieve lower latency and higher throughput.
What is Enhanced Networking in EC2?
Enhanced Networking in EC2 is a way to improve network throughput and reduce the latency by using a dedicated network interface with higher packet-per-second (PPS) performance.
What is an instance store in EC2?
Instance store in EC2 provides temporary block-level storage for instances and is ideal for applications that require high I/O rates and do not need persistent storage.
What is the difference between an EC2 instance and a container?
EC2 instance is a virtual server operating system with the application installed, while a container is a virtualization technology that virtualizes the operating system and its dependencies rather than the hardware.
