Crestline Technologies delivers end-to-end cloud services — Azure migration, Microsoft 365 management, hybrid cloud infrastructure, cloud security, and backup — built for Knoxville SMBs ready to move beyond the limits of on-premises IT.
Every business is different. We help you select and implement the right cloud model for your workloads, compliance requirements, and long-term growth goals.
Leverage Microsoft Azure's global infrastructure for scalable compute, storage, and services — enterprise security with pay-as-you-use economics ideal for growing Knoxville teams.
Dedicated infrastructure with complete control — ideal for businesses with strict data sovereignty, compliance requirements, or sensitive workloads that can't live in shared environments.
Connect on-premises systems with Azure — keeping sensitive workloads local while moving scalable or redundant workloads to the cloud at your own pace.
Strategic use of multiple platforms — Azure for core workloads, M365 for productivity, and specialized services where they make sense — managed as a single unified environment.
From initial migration planning through ongoing management and security — we handle every layer of your cloud environment so your team can focus on what matters.
Discovery, inventory, and phased roadmap development — so you know exactly what's moving, when, and what it costs before a single server is touched.
Lift-and-shift or replatform your on-premises servers and databases to Azure — minimal downtime, verified data integrity, documented cutover plans.
Modernize and migrate line-of-business applications — lift-and-shift, replatforming, or cloud-native rearchitecting — based on what makes sense for each workload.
Design and deploy scalable, resilient Azure infrastructure — virtual machines, virtual networks, storage, and load balancing configured for your workloads and budget.
Automated, repeatable infrastructure deployment using Azure ARM templates and Terraform — environment consistency, version control, and rapid provisioning.
Dynamic resource allocation that adjusts automatically to demand — consistent performance during traffic spikes without over-provisioning during quiet periods.
Security-first cloud configuration from day one — closing misconfigurations, enforcing least-privilege access, and applying Microsoft security baselines to every environment.
Zero-trust access enforcement with Entra ID, Conditional Access, MFA, and Privileged Identity Management across your entire Azure and M365 environment.
End-to-end data protection with Azure Key Vault, encryption at rest and in transit, and Microsoft Purview DLP policies — critical for HIPAA, PCI DSS, and CMMC compliance.
Continuous monitoring of your Azure environment — CPU, memory, disk, network, and security alerts — with proactive response before small issues become outages.
Automated Azure Backup and Site Recovery with tested runbooks — so when something goes wrong, you recover in minutes, not days.
Right-size your Azure spend with reserved instance planning, idle resource cleanup, and monthly cost reviews — never paying for capacity you don't use.
Move from on-premises Exchange, Google Workspace, or other platforms to Microsoft 365 — fully configured, security-hardened, and ready from day one.
Full lifecycle M365 tenant management — user provisioning, license management, Exchange Online, Entra ID, and security configuration as part of your managed IT plan.
Harden your M365 environment against phishing, account takeover, and data leakage — Microsoft Defender, MFA enforcement, and Purview data governance included.
We specialize in Microsoft's cloud ecosystem — deep Azure and M365 expertise — and support hybrid and multi-cloud environments for businesses that need flexibility.
Our primary cloud platform — Azure Virtual Machines, Azure SQL, Backup, Entra ID, Defender for Cloud, and the full Microsoft intelligent cloud stack for East Tennessee businesses.

Medical Practice Running Out of On-Premises Server Capacity
A Knoxville medical group had aging on-prem servers, no off-site backup, and was facing a hardware refresh costing $80K+. Patient records were at risk with no tested disaster recovery plan.
Migrated all workloads to Azure with HIPAA-aware configuration, Azure Backup with daily off-site replication, and Defender for Cloud monitoring. Hardware refresh avoided — ongoing costs cut by 35%.
Law Firm Still on On-Premises Exchange With No Remote Work Capability
A mid-sized East Tennessee law firm was managing their own Exchange Server, dealing with spam, outages, and an inability to work remotely securely. Attorneys were using personal email for client matters.
Migrated to Microsoft 365 with Exchange Online, configured Conditional Access and MFA, deployed Intune for device management, and enforced Purview retention policies for legal compliance.
Manufacturer Needs Cloud Scalability Without Losing On-Floor Systems
A regional manufacturer needed cloud-based ERP and collaboration tools but had floor systems and legacy applications that had to stay on-premises. A full cloud migration wasn't an option.
Designed a hybrid architecture with Azure Arc connecting on-prem and cloud workloads under unified management. ERP moved to Azure; floor systems stayed local — all monitored from a single pane of glass.
Growing Contractor Overpaying for Underused Azure Resources
A construction company had moved to Azure on their own but had no cost governance in place. Their Azure bill was growing 15% month-over-month with idle VMs, orphaned disks, and no reserved instances.
Conducted a full Azure cost audit, rightsized running VMs, cleaned up orphaned resources, and purchased reserved instances for stable workloads. Monthly Azure spend reduced by 42% in 60 days.
No surprises, no big-bang cutovers, no disappearing after go-live. Our four-step process keeps your team productive throughout every migration.
We inventory your current environment, identify cloud-ready workloads, assess security gaps, and build a phased roadmap with timelines and cost estimates. Written findings delivered before any work begins.
We architect your target Azure environment, define your security baseline, configure your Microsoft 365 tenant, and establish backup and disaster recovery strategy — before a single workload moves.
Phased migration with defined cutover windows minimizes downtime and gives your team time to adapt. Each wave is tested and validated before the next begins. Rollback plans documented for every phase.
Ongoing monitoring, security hardening, cost optimization, and support as part of your CrestOne managed IT plan. We don't hand off and disappear — we stay engaged long after go-live.
