Enterprise Challenges

Challenges We Solve

Migrations That Stall Mid-Project

Discovery gaps surface hidden dependencies, undocumented data volumes, and compliance requirements mid-migration — blowing up fixed-price estimates and timelines that weren't scoped with proper workload discovery.

Lift-and-Shift That Doesn't Deliver Cloud Economics

Rehosting applications without right-sizing or re-architecting moves the same inefficiencies to a more expensive platform. Organizations that skip modernization planning see cloud bills grow faster than on-prem costs ever did.

Multi-Cloud Sprawl Without Governance

Teams adopting AWS, Azure, and GCP independently for different workloads end up with inconsistent security policies, duplicated tooling, and no unified cost visibility — multi-cloud without governance is worse than single-cloud.

Compliance Requirements Blocking Cloud Adoption

HIPAA, PCI-DSS, SOC 2, and FedRAMP requirements stall cloud initiatives when compliance architecture is treated as a post-migration add-on rather than a day-one design constraint.

Kubernetes Complexity Outpacing Team Capacity

Adopting Kubernetes without dedicated platform engineering expertise leads to misconfigured clusters, security gaps, and an operational burden that outweighs the orchestration benefits it was meant to deliver.

Cloud Costs Growing Faster Than the Business

Without FinOps practice — right-sizing, reserved capacity planning, and usage accountability — cloud spend scales with infrastructure sprawl rather than with actual business growth.

What We Deliver

Core Capabilities

01

Cloud Migration Engineering

Lift-and-shift, replatforming, and full application refactoring across AWS, Azure, and GCP, sequenced by business risk and dependency mapping rather than technical convenience.

02

Cloud-Native Modernization

Re-architecting monolithic applications into containerized, serverless, or microservices-based systems that reduce ongoing cloud spend by 30-60% versus lift-and-shift alone.

03

Multi-Cloud & Hybrid Architecture

Unified governance, identity, and cost-management layers across AWS, Azure, and GCP, or hybrid architectures integrating on-premises infrastructure via Azure Arc, AWS Outposts, or GCP Anthos.

04

Kubernetes Platform Engineering

Production-grade EKS, AKS, and GKE cluster design with autoscaling, observability, and security baselines — built for teams that need Kubernetes without hiring a dedicated platform team first.

05

Cloud FinOps & Cost Optimization

Right-sizing, reserved instance and savings plan strategy, and usage accountability frameworks that typically reduce cloud spend 20-40% within the first 90 days of production traffic.

06

CI/CD & DevOps Pipeline Engineering

Infrastructure-as-code (Terraform, CloudFormation), automated deployment pipelines, and observability stacks that reduce deployment friction and incident response time.

07

Cloud Security & Compliance Architecture

IAM design, encryption, audit logging, and compliance control implementation for HIPAA, PCI-DSS, SOC 2, and FedRAMP — designed in from the landing-zone stage, not retrofitted.

08

Cloud Data Infrastructure

Cloud-native data pipeline and warehouse architecture that pairs directly with our Data Engineering & Analytics Development Services for teams migrating data platforms alongside applications.

Enterprise Use Cases

FAQ

Common Questions

A single non-critical workload typically migrates in 4-8 weeks. A mid-scale migration of 10-25 workloads runs 12-24 weeks. Enterprise migrations of 50+ workloads run 12-24+ months across multiple waves. See our Cloud Migration Cost guide for a full timeline breakdown by workload count.

Cloud migration ranges from $20,000 for a single-workload proof of concept to $5M+ for a full enterprise portfolio migration. Modernization projects that refactor to cloud-native architecture typically run $50,000-$1M+ depending on scope. We scope every engagement in phases so you can validate value before committing to the full program.

It depends on your existing stack, compliance requirements, and team expertise. Azure fits Microsoft-centric enterprises; AWS fits diverse, cloud-native stacks with the broadest service catalog; GCP fits data-engineering-heavy workloads and Kubernetes-native teams. See our AWS vs Azure, Azure vs GCP, and AWS vs Azure vs GCP comparisons for a detailed breakdown.

Yes. Multi-cloud is increasingly common for organizations with genuinely distinct workload needs — for example running core systems on Azure and data analytics on GCP. We design the governance, cost-tracking, and identity layers that make multi-cloud manageable rather than chaotic.

Yes. We've delivered HIPAA-compliant migrations for healthcare systems and PCI-DSS-compliant infrastructure for payment processors. Compliance architecture is designed at the landing-zone stage, before any workload migration begins, not retrofitted afterward.

Yes. We design and can operate production-grade EKS, AKS, or GKE clusters, and we train your engineering team to take over operations progressively rather than creating a permanent dependency.

For critical systems, yes — using blue-green deployment, database replication, and shadow traffic validation before cutover. Not every workload requires this level of engineering investment; we scope the approach to the actual business risk of downtime for each system.

Through right-sizing based on real post-migration usage data, reserved instance or savings plan commitments after the first 90 days of production traffic, and ongoing FinOps governance. Most clients see 20-40% cost reduction within the first two quarters post-migration.

Both. Startups typically start with a single-workload proof of concept or a serverless-first architecture that avoids over-provisioning from day one. Enterprise engagements involve multi-wave migration planning and compliance architecture — the same engineering team and standards apply to both.

A time-boxed assessment (typically 2-4 weeks) mapping your workloads, dependencies, data volumes, and compliance requirements — under mutual NDA before any sensitive infrastructure details are shared. Discovery produces a scoped proposal, not an open-ended engagement.

Migration moves a workload to the cloud, often with minimal changes (lift-and-shift). Modernization re-architects the application to use cloud-native patterns — containers, serverless, managed databases — which costs more upfront but reduces ongoing cloud spend by 30-60%. Most clients migrate first, then modernize high-value workloads over 12-24 months.

Post-migration support includes performance monitoring, cost optimization reviews, and incident response during the hypercare period immediately following cutover. Longer-term FinOps and platform-engineering retainers are available for teams that want continued optimization as usage grows.
