Eleven practices. One engineering standard.
Each Karell practice is led by senior engineers, validated against reference architectures, and operated under a single delivery model.
Enterprise Infrastructure
Legacy compute and storage stacks throttle business growth and create unpredictable downtime risk.
Modern, software-defined compute and storage platforms designed for high availability and linear scale.
- Up to 99.999% availability
- 30–50% lower TCO
- Predictable performance at scale
- Single-pane observability
- 1Architecture assessment
- 2Reference design & BOM
- 3Phased migration
- 4Lifecycle support
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Networking
Branch, campus and cloud edges have diverged — leaving inconsistent performance and security policy.
Unified SD-WAN, campus and data-centre fabrics with centralised policy and segmentation.
- Application-aware routing
- Zero-touch site rollout
- Encrypted east-west traffic
- Visibility from edge to cloud
- 1Discovery & traffic baseline
- 2Topology & policy design
- 3Cutover with zero downtime
- 424×7 operations
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Cybersecurity
Perimeter-era controls don't survive a hybrid, identity-driven attack surface.
Zero-trust architecture spanning identity, endpoint, network, cloud and data — with a 24×7 SOC.
- Continuous threat detection
- Mean-time-to-respond under 15 min
- Compliance-aligned controls
- Phishing & breach reduction
- 1Risk & maturity assessment
- 2Zero-trust roadmap
- 3Controls implementation
- 4SOC, IR & tabletop exercises
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Cloud
Cloud spend grows faster than business value, and migrations stall halfway through.
Hybrid and multi-cloud strategy, application modernization and FinOps-driven optimization.
- Validated landing zones
- Up to 35% cost reduction
- Faster release velocity
- Resilient multi-region patterns
- 1Cloud readiness review
- 2Landing-zone build
- 3Migration waves
- 4Continuous FinOps
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Data Centre
Aging facilities can't meet density, power and resilience demands of modern workloads.
Design, build and modernization of Tier-III/IV equivalent data centres with HCI and software-defined fabric.
- Higher rack density
- Energy-efficient cooling
- DR & active-active design
- Vendor-neutral architecture
- 1Feasibility & site survey
- 2Design & engineering
- 3Build & commissioning
- 4Operations transition
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Backup & DR
Recovery objectives are aspirational, not tested. Ransomware exposure is high.
Immutable backups, air-gapped copies, and validated DR runbooks tested every quarter.
- RTO/RPO defined & tested
- Ransomware-resilient
- Cross-region replication
- Audit-ready evidence
- 1Data classification
- 2DR design
- 3Implementation
- 4Tabletop & live drills
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Virtualization
Hypervisor lock-in and complex licensing inflate cost and limit portability.
Modern HCI and container platforms aligned to your application portfolio.
- License optimization
- Operational simplicity
- Container-ready
- Workload mobility
- 1Workload profiling
- 2Platform selection
- 3Cutover & validation
- 4Optimization
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Managed Services
Internal teams firefight instead of innovating; vendor sprawl makes accountability fuzzy.
24×7 NOC/SOC with SLA-backed operations across infrastructure, network, security and cloud.
- SLA-backed outcomes
- Single accountable partner
- Predictable OPEX
- Continuous improvement
- 1Transition & runbooks
- 2Operate & monitor
- 3Quarterly reviews
- 4Continuous optimization
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Physical Security
Physical and cyber security operate in silos — leaving blind spots and slow response.
Unified physical security: surveillance, access control and analytics, integrated with cyber SOC.
- Unified incident view
- AI-based analytics
- Compliance-grade audit trails
- Faster response
- 1Site assessment
- 2System design
- 3Installation & integration
- 4Managed monitoring
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
Collaboration
Hybrid work tools are fragmented and underused, hurting productivity.
Unified communications, video, AV and modern workplace — secure by default.
- Frictionless meetings
- Single identity & policy
- Enterprise-grade AV
- Higher adoption
- 1Workplace assessment
- 2Design & pilot
- 3Rollout & adoption
- 4Managed support
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
IT Consulting
Transformation initiatives stall without an architecture-led, outcome-driven plan.
Architecture, advisory and program leadership from engineers who've built it before.
- Outcome-aligned roadmap
- Risk-adjusted plan
- Independent advice
- Board-ready artifacts
- 1Discovery
- 2Roadmap
- 3Business case
- 4Execution oversight
A reference architecture and engagement plan, sized to your environment, with measurable success criteria.
