Frequently Asked Questions
What is cloud consulting and why does it matter?
Cloud consulting gives companies a clear path through strategy, migration, modernization, and ongoing optimization. I think it matters because the right guidance turns a complex transformation into a structured program with predictable outcomes. Strong partners help teams avoid trial-and-error decisions that usually slow progress and drain budgets.
How do I select the right partner?
Start with the basics. Look at certifications, sector experience, and proven delivery across projects that resemble your own. Ask for reference calls, ask for detailed scopes, and study how each firm handles long-term support. I believe these checks reveal more than any glossy presentation.
Which certifications matter most?
AWS Premier or Advanced Tier signals deep capability. Azure Premier or Elite shows maturity on Microsoft-focused work. Google Cloud Premier helps validate engineering strength for GCP programs. These badges don’t solve everything, though they quickly show who plays at enterprise level.
What questions should I ask candidates?
Ask how they handled projects in your sector, how they structure security, and how they measure success once work goes live. Ask about handover, team training, and operational readiness. Those conversations uncover the real story behind each proposal.
What role does AI play?
AI now shapes architecture decisions, migration pipelines, modernization assessments, and cost-optimization steps. I think strong partners use AI to raise delivery quality and cut unnecessary manual work. As the saying goes, the early bird catches the worm, and firms that mastered AI already give their clients a clear edge. A small bonus thought: AI helps cloud projects run smoother, though it still can’t make coffee during late-night go-live calls.
