A practical overview of how AWS is organised: accounts and Organizations, IAM identity, regions and availability zones, core services by category, billing, budgets, and the service quotas that shape every account.
How Google Cloud is organised: projects, folders, and the organization resource, billing accounts and credits, Cloud IAM roles, regions and zones, and the compute, data, and AI services teams use most.
How Microsoft Azure is structured: Entra ID tenants, subscriptions, resource groups, Azure RBAC, regions and availability zones, core compute, storage, database, and AI services, plus billing, budgets, and quotas.
DigitalOcean Droplets explained: teams and projects, shared and dedicated CPU plan families, images, snapshots and backups, regions, VPC networking, Droplet limits, billing, and the port 25 policy.
Linode (Akamai Cloud) explained: account users and permissions, compute plan families, block and object storage, backups, regions, VPC and NodeBalancers, hourly billing, account limits, and SMTP restrictions.
OVHcloud explained: the account and Control Panel, the Public Cloud, VPS, and Bare Metal product lines, OpenStack projects, storage and managed services, European regions, vRack networking, quotas, billing, and SMTP rules.
Oracle Cloud Infrastructure explained: tenancies and compartments, OCI IAM policies, regions, availability domains and fault domains, compute shapes and OCPUs, Autonomous Database, Free Tier, pay-as-you-go billing, and limits.
How Amazon SES is organised: verified identities, the sandbox and production access request, sending quotas and send rate, the SMTP and API interfaces, and the authentication and anti-spam compliance work.
Hetzner Cloud explained: accounts and projects, CX, CPX, CCX, and CAX server types, Volumes, Snapshots and Backups, locations and network zones, Firewalls and Load Balancers, hourly billing, project limits, and port 25.
How UpCloud is organised: accounts and sub-accounts, zones, Cloud Servers and MaxIOPS block storage, private networking, managed databases and Kubernetes, and how hourly billing and prepaid credit work.
How IBM Cloud is organised: account types and enterprise hierarchy, resource groups and IAM, multizone regions versus classic data centres, Kubernetes and OpenShift, data services, watsonx, and billing controls.
How Alibaba Cloud is organised: the international site and console, RAM users and roles, regions and zones including ICP rules, ECS instance families, images, disks, VPC networking, billing modes and quotas.
Planning, cost control, provider choice, research computing, email and account handover for teams.
A practical infrastructure plan for early-stage startups on AWS, Google Cloud, or DigitalOcean: account structure, one deployment pattern, a minimum managed stack, cost controls, access that survives hires, and a phased checklist.
Ten practical habits that keep cloud bills predictable on Azure, Oracle Cloud, and Hetzner: budgets, tagging, weekly bill reviews, right-sizing, scheduled shutdowns, spot capacity, retention rules, egress, and commitments.
When a small team benefits from more than one cloud provider and when it only adds duplication: geography, data residency, unique services, and credits versus doubled IAM, networking, egress, and on-call knowledge.
How to choose a cloud provider for a business: start from your workloads, answer seven deciding questions, compare Google Cloud, IBM Cloud, and OVHcloud profiles, score a shortlist, and run a short evaluation.
Accounts, quotas, credits, pricing models, storage and networking explained across providers.
What a cloud account really contains: resources, identity, billing, and quotas. How AWS accounts, Google Cloud projects, and Azure subscriptions differ, and what to review when you take one over.
IaaS, PaaS, and SaaS define how much of the stack you run versus the provider. See where AWS, Google Cloud, Azure, DigitalOcean, Hetzner, and Google Workspace fit, and how to choose a layer.
Regions and availability zones decide latency, price, quotas, data residency, and fault tolerance. How AWS, Google Cloud, Azure, DigitalOcean, Hetzner, and BinaryLane structure locations, and how to choose.
A vCPU is a share of a physical processor, not a whole core. Learn how shared, dedicated, and burstable vCPUs differ, how vCPU quotas work, and how to size a cloud server.
Deploying servers, containers, Kubernetes, infrastructure as code, CI/CD, serverless and GPU work.
A practical checklist for deploying a first cloud server on DigitalOcean, Vultr, Hetzner, or any VPS provider: region, image, sizing, SSH hardening, firewalls, private networking, backups, and alerts.
How SSH key authentication works, how to generate an Ed25519 key pair, where to add public keys on Linode, UpCloud, Kamatera, EC2, Compute Engine, and Azure, and how to rotate keys safely.
Install Docker on a DigitalOcean, Hetzner, or BinaryLane VPS, lock down port publishing and the Docker socket, run a stack with Compose, and manage volumes, backups, and image updates.
A practitioner's comparison of EKS, GKE, AKS, DOKS, LKE, and IKS: what managed covers, identity and networking integration, control plane pricing models, quotas, and a security baseline.
Port 25, SPF, DKIM, DMARC, deliverability, and SMTP versus API sending.
Why cloud providers restrict outbound port 25 on new accounts, what ports 587 and 465 are for, how authenticated relays and Amazon SES replace direct delivery, and how providers handle lift requests.
How SPF, DKIM, and DMARC work, what alignment means, how to configure them for Amazon SES and Google Workspace, and a safe rollout order from p=none to p=reject.
How transactional and marketing email differ in triggers, consent, volume, and reputation, why they need separate sending identities, and how to run both on Amazon SES.
How sender reputation is built and lost, why new IPs and domains need warm-up, how to handle bounces and complaints automatically, and the list hygiene that keeps mail in the inbox.
How each listed provider organises accounts, regions, billing and services, written for practitioners.

MFA, IAM, VPS hardening, secrets, audit logs and acceptable use policies.
The three controls that stop most cloud account compromises: MFA on the root identity, roles instead of long lived keys, and least privilege on AWS, Google Cloud, and Azure, plus a takeover checklist.
How identities, groups, policies, and scopes fit together in AWS IAM, Google Cloud IAM, Azure RBAC, Oracle Cloud compartments, and IBM Cloud access groups, with patterns that work on every provider.
Harden a Linux VPS on DigitalOcean, Hetzner, or BinaryLane with a provider firewall and ufw, key only SSH, Fail2ban jails for public services, and unattended security updates that keep packages patched.
Where cloud secrets belong: AWS Secrets Manager, Parameter Store, Google Secret Manager, and Azure Key Vault, scoped API tokens on Vultr and Linode, delivery to applications, rotation, and leak detection.
