BigQuery is GCP’s serverless data warehouse designed for large-scale analytics using SQL. It is optimized for high-speed query performance on petabytes of data.
Cloud Run is for containerized applications, offering flexibility in language and runtime. App Engine is for managed applications where the platform handles scaling and updates automatically.
Common issues include incompatible APIs, data transfer costs, and re-architecting apps. Testing and phased migration help reduce downtime and risk during transitions.
GCP provides infrastructure, platform, and software services for compute, storage, networking, and AI. It powers products like YouTube and Gmail, and supports enterprise workloads.
A three-tier architecture separates presentation, application, and data layers. It improves scalability, maintainability, and fault isolation.
The three main cloud service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). RAAS is not a standard model in cloud computing.
AWS CloudFormation allows you to define and provision infrastructure using JSON or YAML templates. It treats infrastructure as code, ensuring consistency across environments.
Ansible is an agentless automation tool that uses SSH to configure servers. Its YAML-based playbooks make it simple to read, write, and reuse across environments.
Ansible is used for configuration management, app deployment, and environment setup. In cloud DevOps, it automates repetitive tasks like installing dependencies or updating servers after deployment.
Amazon S3 (Simple Storage Service) stores objects like images, videos, and backups. It’s highly durable and accessible via REST APIs from anywhere.
Azure Virtual Machines allow you to deploy Windows or Linux instances in the cloud. They support scaling, snapshots, and integration with networking and storage.
Azure App Service is a fully managed PaaS offering to host web and mobile apps. It automatically handles scaling, load balancing, and security patches.
Azure Functions is a serverless compute service that runs event-driven code without managing infrastructure. Use it for background jobs, file uploads, scheduled tasks, or API event handling.
GCP uses a consumption-based model — you only pay for what you use. You can combine sustained use discounts and committed use savings for better cost control.
Subnets divide your VPC into smaller address spaces for better organization and security. You can use public subnets for internet-facing resources and private ones for internal servers.
