Cloud Computing Masterclass - Deployment to Administration

Explore platform as a service (PaaS), where a cloud provider manages software, operating system, middleware, runtime, storage and backups, enabling DevOps collaboration and scalable, rapid deployment.

Explore software as a service, a cloud-hosted app model offering ready-to-use, subscription-based apps via web, desktop, or mobile. Vendors manage infrastructure, data, middleware, upgrades, patches, and security.

Explore the Linode cloud manager dashboard to manage virtual instances, storage volumes, object storage, and marketplace components, while navigating account settings and support resources.

Explore the Linode instance dashboard to manage a deployed test vm, review analytics, networks, volumes, configurations, backups, and settings, and execute ssh access and admin tasks.

Learn to generate a 4096-bit ssh key pair on windows using putty gen and putty, configure the server for key-based authentication, and securely connect to a node instance.

Add SSH public keys to the node cloud manager, label and paste your key to enable future instance deployments; during deployment, select the key to provision access.

Create a non root user named Bob, set a password, and add him to the sudo (pseudo) group to grant superuser privileges; verify the user and group membership.

Secure a non-root user by generating a new ssh key pair, configuring bob's .ssh and authorized_keys with proper permissions, and logging in via the private key to gain sudo access.

Explore software stacks such as lamp, mean, and merlin stacks, and learn how Linux, Apache, MySQL, PHP, React, and Express support web applications.

Differentiate frameworks from libraries, noting inversion of control and a framework’s opinionated flow, with examples like React JS, Angular JS, Express JS, Django, Flask, Laravel, Igniter, and Cake.

Install and configure a complete lamp stack on ubuntu by setting up apache, MariaDB, and PHP, securing the database, and verifying the web server with the default Apache page.

Discover installing the lamp stack via the marketplace one-click apps during deployment, configuring root password and ssl, and choosing image and region. Verify with browser; post-deployment customization is not supported.

Learn how to connect a PHP script to a MariaDB database and manage it with a dedicated non-root user. Create a database, grant privileges, and run insert and select queries.

Learn foundational server security principles for hosting web apps, including Apache configuration, firewall setup, and network monitoring, and mitigate DDoS, directory traversal, and brute-force attacks.

Configure a hosted firewall on ubuntu with ufw, set default deny, allow ssh on a custom port, and permit http, https, dns, and db traffic, working alongside a network firewall.

Enable the backup service for an instance, take manual and automated snapshots with a three-slot rotation (daily, 2–7 days, 8–14 days), and understand the $5-per-month cost.
