EC2, or Amazon Elastic Compute Cloud, is a web service that provides resizable compute capacity in the cloud, allowing users to run virtual servers and manage applications on-demand.
Availability Zones are isolated locations within a Region that provide high availability and fault tolerance. A Region is a geographical area that contains multiple Availability Zones, allowing for resource distribution and redundancy across different physical locations.
Amazon CloudWatch is a monitoring and management service that provides data and insights about AWS resources and applications, allowing users to collect and track metrics, set alarms, and automate responses to changes in their AWS environment.
To secure data in transit in AWS, use SSL/TLS for encryption during transmission and implement VPNs or AWS Direct Connect for secure connections. To secure data at rest, use AWS services like S3 Server-Side Encryption, EBS encryption, and RDS encryption, along with IAM policies to control access.
Auto Scaling is a feature in AWS that automatically adjusts the number of EC2 instances in a group based on demand, ensuring optimal performance and cost efficiency.
Cloud NAT (Network Address Translation) is a Google Cloud service that allows private IP instances to access the internet for outbound traffic without exposing their private IP addresses. It enables these instances to communicate with external services while keeping them secure and private by translating their private IP addresses to a public IP address for outbound requests.
You would choose BigQuery over Cloud SQL or Firestore when you need to analyze large datasets quickly, perform complex queries on massive amounts of data, or require advanced analytics features like machine learning and real-time data processing.
App Engine Standard is designed for applications that require rapid scaling and are built on specific languages and frameworks, while App Engine Flexible allows for more customization, supports a wider range of programming languages, and provides more control over the underlying infrastructure.
A VPC (Virtual Private Cloud) in GCP (Google Cloud Platform) is a virtualized network that allows you to create and manage your own private network within the Google Cloud environment. It enables you to define IP address ranges, create subnets, configure firewalls, and manage routing. VPCs provide isolation and control over your resources, allowing them to communicate securely within the network and with external networks.
Preemptible VMs in GCP are short-lived, cost-effective virtual machines that can be terminated by Google Cloud at any time if resources are needed for other tasks. They are ideal for batch processing and fault-tolerant workloads.
