1 - What is AWS?
Amazon Web Services (AWS) is a cloud services platform provided by Amazon that offers a mixture of infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) offerings. It provides a wide range of cloud computing services, including computing power, storage options, networking, databases, machine learning, and analytics tools.
2) What are the key components of AWS?
AWS comprises numerous services and features, including Elastic Compute Cloud (EC2) for scalable computing capacity, Simple Storage Service (S3) for scalable object storage, Lambda for serverless computing, Virtual Private Cloud (VPC) for isolated cloud resources, and Amazon RDS for managed relational databases. These components form the foundation for building and managing various types of applications and workloads in the cloud.
3) How can you ensure the security of data in AWS?
To enhance data security in AWS, best practices include implementing multi factor authentication (MFA), encrypting data at rest and in transit using AWS Key Management Service (KMS), setting up access controls with Identity and Access Management (IAM), regularly auditing and monitoring AWS resources with services like CloudTrail and Config, and applying security patches and updates to AWS services.
4) Explain the difference between scaling horizontally and vertically in AWS.
Scaling horizontally (or scaling out) in AWS involves adding more instances or resources to distribute the workload, while scaling vertically (or scaling up) involves increasing the capacity of existing resources such as upgrading the size of an instance or adding more memory or CPU to handle increased demand.
5) What is the difference between Amazon S3 and EBS in AWS?
Amazon S3 (Simple Storage Service) is an object storage service that allows data storage and retrieval from anywhere on the web, while Amazon EBS (Elastic Block Store) provides block level storage volumes for EC2 instances, offering persistent, low latency storage volumes that can be attached to instances for data storage needs requiring frequent updates.
