Top Cloud Consulting & SI Companies

Cloud consulting and systems integration (SI) firms plan and carry out the move of applications and data to AWS, Azure or Google Cloud, then connect it to the systems a company still runs on premises. The work spans readiness assessments, landing zone design, migration waves, identity and access, cost governance, and the integration that keeps ERP, CRM and data platforms talking. IT directors hire them when a data center lease ends, when a merger leaves two estates to combine, or when cloud bills climb.

Compare the firms here on partner tier with your chosen hyperscaler, on reference migrations of similar size and regulatory load, on whether they hand back infrastructure as code, and on reviews that talk about cost after go-live.

Buyer's guide

Hiring Cloud Consulting & SI companies

What the work covers, how to judge a partner and what drives the price.

What cloud consulting and SI firms do

Consulting work starts with an assessment: an inventory of applications and their dependencies, and a recommendation per workload to rehost, re-platform, refactor, replace or retire. Design follows: a landing zone with accounts, networking, identity, logging and guardrails; a security and compliance posture mapped to SOC 2, ISO 27001, HIPAA or PCI DSS where required; and a data platform plan. The integration half covers API gateways, integration platforms, connectors to ERP and CRM systems, identity federation, and the message and file flows between what moved and what stayed.

Engagements are sold as fixed-fee assessments, fixed-scope migration programs priced per wave or per workload, time-and-materials architecture and engineering, and managed services that run and optimize the estate after go-live for a monthly fee. Hyperscaler partner programs often fund part of an assessment or migration.

A typical program moves from discovery and business case, through landing zone build and a pilot wave of low-risk workloads, then migration waves with cutover rehearsals, to decommissioning and a cost optimization pass once the estate has settled.

Cloud Consulting & SI FAQs

Short answers to what buyers ask before hiring a Cloud Consulting & SI company.

Question not covered? Ask our team

A cloud consulting and SI firm assesses which applications and data should move to AWS, Azure or Google Cloud, designs the landing zone, security and networking they will run on, carries out the migration in waves, and integrates the cloud estate with the ERP, CRM and data systems that remain. Many also run and cost-optimize the environment afterward under a managed services agreement.

Cloud consulting is sold as fixed-fee assessments, per-wave or per-workload migration prices, day-rate engineering and monthly managed services, with hyperscaler funding sometimes covering part of the bill. Costs rise with workload count, data volume, downtime tolerance, refactoring depth, integration points and compliance evidence. Most firms on this page set a minimum project of $1,000 to $10,000, and migration specialists start at $25,000 to $50,000.

Duration is set by the number of workloads, how well their dependencies are known, and how much downtime the business can accept. The phases are discovery and business case, landing zone build, a pilot wave, production waves with cutover rehearsals, decommissioning and optimization. Undocumented dependencies, large data transfers, licensing constraints on legacy software and slow security sign-offs lengthen it most. Ask for a wave plan that names the applications in each wave.

Choose on partner tier with your chosen hyperscaler, references that match your workload mix and regulatory setting, engineers who build infrastructure as code you will own, a written rollback and cutover plan, clarity on who holds administrative accounts, and transparency on any reseller margin. Reviews that mention cloud costs after go-live and the handover of runbooks are the most telling.

A cloud consultant advises: assessment, architecture, migration strategy and governance. A systems integrator builds and connects: landing zones, migrations, and the integration of cloud platforms with ERP, CRM, identity and data systems. Firms in this category do both, which is why the listing name joins them. A pure consultant suits a company with its own engineers; an integrator suits one that needs the work done and the systems wired together.

Firms in this listing most often serve information technology, financial services, healthcare, business services, ecommerce, manufacturing, education and retail. Financial and healthcare buyers need partners fluent in compliance evidence and data residency; manufacturers typically combine cloud with ERP and plant-system integration; ecommerce and retail buyers prioritize elasticity for seasonal traffic and integration with order and inventory systems.

The largest clusters of cloud consulting and SI firms on this page are in London, Ahmedabad, Bengaluru, New York and Pune, with Noida, Dubai and Toronto following. London, New York and Toronto host partner-tier consultancies serving regulated clients; Bengaluru, Pune, Ahmedabad and Noida hold the large delivery and managed services teams. Filter by city when data residency, time zone overlap or on-site cutover support matters.
