The library
Everything you need to plan the move
Six categories, one honest field guide. Start with the strategy, or jump straight to the task in front of you.
Cloud providers
Should you, and how do you, move to AWS, Azure, or Google Cloud.
Migration playbooksThe strategy: how to plan and run a migration end to end.
Migration guidesTask-level how-tos for the concrete moves.
Cloud cost & FinOpsEstimate it, compare it, and keep it from exploding.
Cloud securityWho secures what, and how to lock down day one.
Cloud glossaryPlain-language definitions of the terms that trip people up.
The migration journey
Five phases, in the right order
Every successful migration we have run follows the same arc. Skip a phase and it finds you later, usually in the bill.
Phase 01
Assess what you run
Inventory your workloads, dependencies, and true on-premise costs. You cannot plan a move you have not measured.
On-premise vs cloud TCO → Phase 02
Choose the provider
Compare AWS, Azure, and Google Cloud on the criteria that matter for your stack, not on the marketing.
How to choose a provider → Phase 03
Set the strategy
Decide which of the 6 Rs applies to each workload, sequence the moves, and set a timeline you can defend.
Cloud migration strategy → Phase 04
Make the move
Execute in waves with tested rollback paths. Done well, your users never notice the cutover happened.
Zero-downtime migration → Phase 05
Tune cost & security
Right-size what you moved, lock down access, and put guardrails on the bill before it grows quietly.
Avoid cloud bill shock →Free assessment
Get a second opinion before you commit.
Tell us what you run and where you want to be. A Webisoft cloud engineer will map the realistic path, timeline, and budget for your stack. Free, and with no sales pressure.
Providers
Every major cloud, covered honestly
In-depth guides to five providers: what each is genuinely good at, how its pricing really behaves, and when it is the wrong choice. We resell none of them.
Start here
The guides most teams read first
Cornerstone playbooks and guides that answer the questions every migration starts with.
The three ways to move an app to the cloud, compared on cost, risk, and time-to-value, plus a decision framework and worked numbers for each path.
A vendor-neutral framework for picking between AWS, Azure, GCP, DigitalOcean, and OCI: five factors, a decision table, and why multi-cloud can wait.
Blue-green environments, database replication, DNS traffic shifting, and rollback, the four techniques that let you migrate without taking users offline.
Dump-and-restore vs continuous replication, managed vs self-managed, cutover steps, validation queries, and the rollback plan, a working method for zero-drama database moves.
Who secures what in the cloud: the provider secures the platform, you secure everything you put on it. The IaaS/PaaS/SaaS split, and the misconfigurations behind most breaches.
Cost & FinOps
The bill is the part nobody plans for
Cloud pricing is designed to be easy to start and hard to predict. Egress fees hide until you move data out. Idle instances bill around the clock. And the first invoice after cutover is where most migration regret begins. Our FinOps guides show you how to estimate before you move, and how to keep the meter honest after.
- Estimate your bill before you migrateBuild a real number from your current workloads, not from a pricing calculator demo.
- Compare AWS, Azure, and GCP pricing honestlyWhere the big three actually differ, and where the differences are noise.
- Know when reserved capacity beats on-demandCommitment discounts are real money, and a trap if you commit too early.
- Nine concrete ways to avoid bill shockThe guardrails to set in your first week, before the meter starts running.
Talk numbers
Find out what your migration should actually cost.
Bring your current setup and your target. We will give you a realistic budget range, the hidden line items to watch, and a plan that keeps the first invoice boring.
Why neutral matters
We do not sell cloud. We move you to it.
Most migration advice comes from someone paid to land you on their platform. Ours does not. That changes what we can say out loud.
No reseller margins
We take no commissions and carry no sales quotas with any provider. A recommendation earns us nothing except being right.
Advice from the build side
These guides are written by the engineers who run migrations, not by a content team working from a partner deck.
Honest tradeoffs, in writing
Every provider guide says what the platform is bad at. If a page never says anything negative, it is an ad.
Staying put is an option
If on-premise is genuinely cheaper and safer for your workload, we will say so. Some of the best migrations are the ones you skip.
Who this is for
Written for the person running the migration
Not for procurement, not for the board deck. For whoever has to make the move actually work.
Founders and owners
You have outgrown the current setup and need a straight answer on cost, risk, and timeline before you commit a quarter to this.
Start with the roadmap → CTOs and engineering leads
You own the outcome, the deadline, and the fallout. Use the playbooks to sequence the move and the provider guides to defend the platform choice.
Read the strategy playbook → Ops and platform engineers
You are the one actually moving the database at 2 a.m. The task guides are step by step, tested, and honest about what breaks.

Short, plain-language definitions with a real-world example each. Useful before the vendor calls, decisive during them.
