Which AWS consulting partner is best for migration?

Top migration specialists include Slalom (score 8.9/10) for enterprise migrations, Mission Cloud for lift-and-shift projects, and Caylent for containerization. Budget depends on workload complexity: $200K-$500K for mid-size migrations, $1M+ for enterprise.

How much do AWS consulting services cost?

Typical rates range from $150-$300/hour. Project-based pricing: Discovery assessments $25K-$75K, migrations $200K-$2M+, managed services $5K-$50K/month. Premier partners like Accenture charge premium rates; Select partners like STX Next offer competitive pricing starting at $120K.

What's the difference between AWS Premier and Select partners?

Premier partners have proven expertise across multiple competencies, larger customer bases, and dedicated AWS support. Select partners are specialized in specific areas. Both can deliver quality work—your choice should depend on project needs, not tier level.

Do I need an AWS partner for cloud migration?

Not always. In-house teams can handle simple migrations with AWS tools. Partners add value for: complex architectures, tight timelines, specialized expertise (containers, databases), or when internal resources are limited. ROI comes from avoiding costly mistakes and faster time-to-production.

How long does an AWS migration typically take?

Timelines vary widely: Simple lift-and-shift: 2-4 months, re-platforming: 4-8 months, full modernization: 8-18+ months. Fast-start partners like Cognizant and Wipro can begin in under 30 days. Factor in discovery (4-6 weeks), migration waves, and post-migration optimization.

What should I look for in an AWS managed services provider?

Key criteria: 24/7 support coverage, proactive cost optimization (not just monitoring), security competency, transparent SLAs, and experience with your industry. Check if they have Well-Architected Framework expertise and ask for client references with similar infrastructure.

Can AWS partners help reduce my cloud costs?

Yes. Optimization specialists like DoiT and 2nd Watch focus on cost reduction. Typical savings: 20-40% through rightsizing, reserved instances, and waste elimination. Most charge based on savings (15-25% of identified savings) or fixed monthly fees ($10K-$30K).

What's the typical engagement length with an AWS consulting firm?

Discovery/assessment: 4-8 weeks, migration projects: 3-12 months, managed services: ongoing (12+ month contracts typical). Many firms offer flexible arrangements—from project-based for migrations to long-term managed services. Minimum commitments usually 3-6 months for managed services.
