Project Title: Upgrade of Red Hat Enterprise Virtualization (RHEV)
Scope: Upgrade from RHEV 3.0 to 4.1 on a live production environment
Timeline: 3 working months
Setup:
63 Physical Hypervisors
1 RHEV Manager Node
800+ Virtual Machines
Fully operational 24x7 with strict downtime constraints (Upgrade window: 12
A.M. – 6 A.M. only)
Complex Network & Storage Architecture: The existing environment had deep
integration with custom networking layers and multi-tiered storage, increasing
the upgrade complexity.
Refusal by Previous Support Partner: The incumbent support provider backed
out due to high technical risks.
OEM Timeline Estimate: Even Red Hat’s own experts had estimated 7
months for the upgrade.
High-Risk Environment: Being a production environment, any downtime or
failure posed significant business and reputational risks.
Solution Strategy
The project team approached the upgrade in three strategic phases:
In-depth discovery of network topologies, VM dependencies, and storage
mappings.
Created detailed migration blueprints and rollback plans for each hypervisor
and VM group.
Simulated upgrade in a parallel test environment mirroring production.
Adopted a rolling upgrade methodology to isolate risk and maintain uptime.
Upgrades executed strictly within the approved 12 A.M. to 6 A.M. window.
Developed custom scripts for data migration, version compatibility checks,
and service validation.
Post-upgrade monitoring of performance metrics and service availability.
Fine-tuned hypervisor and VM configurations based on new RHEV 4.1
capabilities.
Conducted load testing and failover simulations to ensure operational
resilience.
Successful upgrade of all 63 hypervisors and 800+ VMs within the planned 3-
month window.
Zero unplanned downtime or data loss during the transition.
Enhanced system performance, stability, and security due to the improved
capabilities of RHEV 4.1.
Restored client confidence and positioned the team as a strategic
infrastructure partner.
Client: Infosys
Project: Private Cloud Implementation Using Canonical OpenStack
Duration: 1 month
Location: India (DC & DR Sites)
The client wanted to move away from legacy virtualization environments and
establish a scalable private cloud platform to host internal and customer-
facing applications with improved automation, monitoring, and cost control.
Solution Provided by TIS Labs:
Designed and deployed Canonical OpenStack with Juju for orchestration and
MAAS for bare-metal provisioning.
Set up Highly Available (HA) control plane across primary (DC) and
secondary (DR) locations.
Integrated Ceph Storage Cluster for unified block and object storage with
redundancy.
Implemented OpenStack Neutron with Calico for SDN-based network
segregation and security.
Integrated Keystone with LDAP for authentication and established Grafana-
Prometheus stack for observability.
Set up DevOps pipelines using Jenkins, GitLab CI, and Terraform for
automated resource provisioning.
Reduced provisioning time from weeks to minutes.
Achieved 99.99% uptime with failover between DC and DR.
Enabled full multi-tenancy with fine-grained quota and role-based access
control.
~30% cost reduction over legacy VMware licensing.
Client: Insurance Information Bureau
Project: Infrastructure Modernization & DC/DR Redesign
Duration: 9 Months
Location: India
The client was running outdated VMware 5.5 clusters and MS SQL/Oracle
databases on unsupported hardware. They faced downtime risks, compliance
issues, and lacked DR synchronization.
Solution Provided by TIS Labs:
Performed comprehensive assessment using RVTools, Runecast, and
database workload analysis tools.
Migrated legacy VMware 5.5 to vSphere 7 environment with vSAN in DC and
DR.
Deployed Zerto for real-time replication and VMware SRM for DR
orchestration and testing.
Migrated MS SQL, Oracle DBs to new infra using Data Guard (Oracle)
and Log Shipping/Always On (SQL).
Enabled active-active replication across DC and DR with RPO < 10 mins and
RTO < 30 mins.
Used Ansible to automate patching and configuration compliance.
Seamless migration with zero data loss and minimal downtime.
Fully DR-ready environment with periodic DR drills.
Achieved >50% performance improvement in DB workloads.
Reduced risk exposure from EOL systems by 100%.
