Managed cloud infrastructure (also called cloud infrastructure services) is the outsourced design, build, and 24/7 operation of a business's cloud environment: compute (Azure VMs, scale sets, App Service), networking (VNets, Private Link, SD-WAN, firewalls), storage, containers and Kubernetes, identity, backup, and disaster recovery. On-Site Technology (OST) delivers managed Microsoft Azure, VMware and Hyper-V private cloud, Tier III co-location, and AI-ready Azure workloads including Azure AI Foundry and Microsoft 365 Copilot readiness across NJ, NY, PA, and FL. Every environment is aligned to NIST SP 800-171, CMMC 2.0 Level 2, HIPAA, and PCI DSS 4.0 for companies with 10 to 500 users. Pricing is scoped to your environment and compliance requirements. Call (973) 777-7227 for a custom quote.

Azure AI Foundry setup, Azure OpenAI deployments on GPT-5.5 and the GPT-5 series, Claude on Azure, plus Microsoft 365 Copilot readiness. Foundation work, not custom agent builds.
The hard part of Azure is not spinning up a VM. It is everything that holds the tenant together once you have one. We design the landing zone, operate the four pillars below, and run FinOps against every dollar.
Every new Azure tenant we deliver starts with a landing zone designed to Microsoft's Cloud Adoption Framework and validated against the Azure Well-Architected Framework. The management-group hierarchy, subscription topology, network hub, shared services, Entra ID policies, and cost guardrails are automated with Bicep or Terraform so your tenant is reproducible, auditable, and free of ad-hoc artifacts that accumulate when engineers spin up resources in a hurry. Defender for Cloud, Sentinel, and Azure Monitor are wired before the first production workload moves. FinOps is part of the managed service, not a separate SKU: right-sizing, reserved-instance coverage, and lifecycle policies get reviewed weekly, and every cost anomaly is named in your monthly report.
Already running on Azure? We offer a no-cost Azure Well-Architected review. Still on-prem? We quote the migration alongside a Microsoft 365 tenant review so identity and cloud line up from day one.
You are already paying for Azure. When your team wants to roll out Microsoft 365 Copilot, build a Copilot Studio agent, or stand up a production Foundry environment, OST handles the foundation so your team can focus on the use case. Three practices, on top of the same managed Azure tenant.
Project and hub provisioning with Bicep or Terraform, private endpoints on every dependency, Content Safety and Prompt Shields, Evaluation SDK for regressions. Honest scope: foundation and ops, not custom multi-agent builds.
Permission audit across SharePoint and OneDrive, Microsoft Purview sensitivity labels, DLP policies, Entra Conditional Access hardening, and Defender for Copilot monitoring. The unglamorous work that prevents Copilot from leaking data on day one.
Microsoft Entra Agent ID provisioning for every Copilot Studio or Foundry agent, quarterly shadow-agent discovery, lifecycle management, and clean deprovisioning for non-human identities in your tenant.
Route the right model to the right task, pay for what you actually use.
Released 2026-04-23. Plus GPT-5.4, 5.3, 5.2, 5.0 for cost-tuned fallbacks.
Long-horizon planning, multi-step tool-use, and problem decomposition.
Via Azure AI Foundry Model Catalog. Strong on tool-heavy and computer-use.
Classification and low-stakes first passes. Low latency, low cost.
Honest scope: OST stands up and operates the AI foundation. Custom multi-agent builds in AutoGen or Semantic Kernel are something your team or a delivery partner does on top. Pair this with our Microsoft Copilot for Business service for rollout and adoption.
Not every workload belongs in public cloud. For regulated, sovereign, or steady-state workloads, we run two alternatives under the same managed service.
Dedicated VMware vSphere or Microsoft Hyper-V clusters sized to your workload. Public-cloud operating discipline, private-cloud economics and isolation.
You own the hardware. We operate the facility. For legacy gear, specialty hardware, or compliance boundaries that require iron you control.
Most mid-market businesses end up hybrid: identity in Entra, productivity in Microsoft 365, business apps in Azure, a private cluster for the ERP, and co-lo for gear not ready to move. OST designs and operates all four under one SLA.
Most businesses need a mix. This is the shorthand we use to help you pick which workload goes where.
| Public Azure | Azure AI Foundry | Private Cloud | Tier III Co-lo | |
|---|---|---|---|---|
| Best for | Elastic business apps, web workloads, M365 estates | Agent-ready AI workloads on GPT-5.5, Claude 4.6, Phi-5 | Regulated or steady-state workloads with known specs | Legacy physical gear, compliance boundaries, sovereignty |
| Cost profile | Variable, consumption-based | Consumption plus token and inference spend | Predictable monthly fee | Predictable monthly plus cross-connect fees |
| AI fit | Moderate. Fine for Copilot, not optimized for custom agents | High. Native Foundry tooling, Content Safety, evals | Low. Possible via Azure Local or on-prem GPUs, heavier lift | Low. Bring your own accelerators, we provide the space |
| Compliance fit | HIPAA, PCI, SOC 2, FedRAMP (public-cloud controls) | NIST AI RMF, ISO 42001, plus the Azure baseline | CMMC 2.0, HIPAA, PCI, and air-gapped patterns | Any framework, subject to tenant design |
| Data sovereignty | Regional, vendor-controlled | Regional, private endpoints, customer-owned data | Full control | Full control |
| Who operates it | OST manages the tenant, you consume it | OST stands up the environment, your team builds on it | OST operates the stack end to end | OST operates the facility, you own the hardware |
Six steps, typical first 90 days. You see every step, every cost, and every rollback point.
Two-week read of your identity, cloud, compliance, and workload plans. We map what you have, what you need, and where the risk is.
Azure landing zone, subscription layout, network topology, and compute patterns designed before we touch production.
Entra, Conditional Access, Defender, and Purview labels in place. Non-negotiable prerequisites before any workload lands.
Workloads move in waves with rollback points. New builds ship on the landing zone. No surprise outages, no weekend hero runs.
Right-sizing, reserved coverage, lifecycle policies on storage, and a weekly cost review that names every anomaly.
24/7 SOC, Azure monitoring, patching cadence, quarterly business reviews, and a single accountable point of contact.
We do not bolt compliance on at audit time. Every cloud environment lands on a baseline aligned to NIST SP 800-53 Rev. 5, NIST SP 800-171 Rev. 3, CMMC 2.0 Level 2, HIPAA, PCI DSS 4.0, SOC 2 Type II, and ISO/IEC 27001:2022.
For AI workloads on Azure AI Foundry we align to the NIST AI Risk Management Framework Generative AI Profile, ISO/IEC 42001, OWASP Top 10 for LLM Applications, and MITRE ATLAS. Defense contractors pair this with our CMMC 2.0 program. Healthcare and finance teams add managed cybersecurity services for SOC, MDR, and penetration testing. Every engagement ships with a ransomware-resilient backup and continuity plan.
Five reasons mid-market businesses in the tri-state and South Florida pick us over a national MSP or a one-size-fits-all hyperscaler reseller.
Founded in 2001. We were managing Exchange servers before there was a cloud. The same senior engineers still pick up.
Compute, networking, storage, containers, identity, backup, and AI-ready workloads. One team across the whole stack, not a reseller middleman.
NJ, NY, PA, and South Florida. We roll a truck when cloud problems turn out to be cabling problems. Most national MSPs cannot.
Every engagement ships with a Copilot readiness review and Foundry-ready identity. When your team is ready for AI workloads, the runway is already built.
Custom pricing scoped to your workload, with no multi-year lock-ins and no surprise invoices when Azure egress spikes.
Every managed cloud engagement is priced to your actual environment: user count, compute footprint, networking, storage, backup, and compliance requirements all factor into the monthly fee. Most mid-market businesses land in a predictable range once we understand the setup. No multi-year lock-ins. No surprise invoices when Azure egress spikes.

Managed cloud infrastructure is the outsourced design, provisioning, security, governance, and ongoing operation of your cloud environment. In 2026 that scope has expanded to include the agent-ready foundation your business needs to safely deploy Microsoft 365 Copilot and custom agents on Azure AI Foundry. OST covers Azure tenant operations, Azure AI Foundry setup, Azure OpenAI model deployments, private cloud, Tier III co-location, and backup and disaster recovery as a single managed service.
OST managed cloud infrastructure pricing is scoped to your environment: the number of users, workloads, compute footprint, compliance requirements, and cloud locations all factor into the monthly fee. Most mid-market businesses land in a predictable range once we understand the setup. Run our free cost calculator for a rough estimate, or call (973) 777-7227 for a custom quote.
The base managed cloud tier covers Azure tenant operations including landing-zone maintenance and policy baseline, Microsoft Entra identity management, Microsoft Defender for Cloud baseline configuration, standard backup with a 30-day retention window, 24/7 monitoring tied into our SOC, a quarterly business review, and a Copilot readiness assessment. Private cloud, HA co-location, and Azure AI Foundry environments are priced on workload and quoted separately. No multi-year lock-in is required on the base tier. Call (973) 777-7227 for a quote scoped to your team size and workloads.
For most 50-person businesses, Azure is the right default because identity, productivity, and AI all converge on Microsoft 365, and the scale economics favor public cloud for variable workloads. Private cloud is the better answer when your workload is steady-state, when compliance rules out multi-tenant hosting, or when you have data sovereignty requirements that public cloud cannot meet. Many of our clients end up hybrid: Azure for productivity and AI, a private cluster for the ERP, and co-location for legacy gear.
Cloud hosting means you rent virtualized compute, storage, and networking from a provider like Microsoft Azure. The provider owns the hardware. Co-location means you own the hardware and rent rack space, power, cooling, and connectivity from a data center operator. OST offers both, plus managed private cloud, which sits in between. The right choice depends on how predictable your workload is, how strict your compliance is, and whether you have existing hardware you need to keep running.
Yes. OST builds Azure environments and private cloud stacks against NIST SP 800-171 Rev. 3 and CMMC 2.0 Level 2 from day one, including enclave design for controlled unclassified information, encryption in transit and at rest, FIPS 140-3 modules where required, Entra Conditional Access, and a defined shared-responsibility matrix mapped to the NIST SP 800-171 Rev. 3 control catalog. We work alongside your CMMC program to provide the evidence a C3PAO assessor will ask for.
Yes. OST designs HIPAA-eligible Azure and private-cloud environments with Business Associate Agreements in place, PHI-aware Purview labels, audit logging through Microsoft Sentinel, and isolation boundaries appropriate to your covered-entity or business-associate status. Copilot and Foundry deployments in HIPAA environments receive additional guardrails including restricted model endpoints and explicit PHI handling policies.
Our standard managed cloud SLA is 99.9%, which maps to roughly 8.76 hours of downtime per year. High-availability architectures across paired Azure regions or dual private-cloud sites can be designed to tighter targets when the workload justifies the added cost. Every SLA comes with clear exclusions, a defined escalation path, and monthly performance reporting.
We pair Veeam with Azure Site Recovery, configure immutable backup repositories, and test restores on a quarterly cadence. Every plan carries an RPO and RTO that you sign off on. Ransomware-specific patterns include air-gapped copies, tamper-proof retention, and rehearsed recovery runbooks. For the full playbook see Backup and Continuity Solutions.
Yes. Most of our mid-market clients are hybrid by design. Identity lands in Entra, productivity in Microsoft 365, AI workloads in Azure AI Foundry, and steady-state or regulated workloads on private cloud or in co-location. We operate all four under a single SLA, a single runbook, and a single point of accountability.
Yes. OST runs Linux workloads on Azure every day: Ubuntu, Red Hat Enterprise Linux, SUSE, Rocky, and Debian. We handle patching via Azure Update Manager, configure SSH key management through Microsoft Entra, wire Defender for Servers onto every instance, and operate Kubernetes clusters on Azure Kubernetes Service (AKS) with Linux node pools. Containerized workloads run on AKS or Azure Container Apps with the same monitoring and security baseline as Windows workloads. Mixed-OS environments are the norm, not the exception.
No multi-year lock-in on the base managed cloud tier. Standard terms are month-to-month after an initial 90-day onboarding period, with 30 days written notice to terminate. If you ever move on, we hand over everything: Azure tenant ownership stays yours throughout, documentation of your landing zone architecture, a clean exit runbook, and assistance with the transition to your next provider. No data is held hostage. Workload-specific agreements for private cloud or co-location may carry longer terms tied to hardware commitments; those are called out clearly up front.
OST services businesses across Northern and Southern New Jersey, New York (including Manhattan, Long Island, and Westchester), Pennsylvania (Philadelphia metro and Bucks County), and South Florida (Broward, Miami-Dade, and Palm Beach). Our cloud platforms are global, but our on-site support, field engineering, and emergency response are regional.
Azure AI Foundry is Microsoft's unified platform for building, deploying, and governing AI applications and agents on Azure. It absorbed Azure AI Studio and now includes Azure AI Foundry Agent Service, a model catalog that hosts OpenAI, Anthropic Claude, and Microsoft Phi models, plus built-in evaluation and safety tooling. Managed Foundry means OST provisions the hub and projects, wires private endpoints, turns on Content Safety and Prompt Shields, and operates the environment so your team can focus on building the agents.
Yes. GPT-5.5 released 2026-04-23 on Azure OpenAI, Claude Opus 4.6 and Haiku 4.5 run via the Azure AI Foundry Model Catalog, and Phi-5 is available as a Microsoft small language model. A good default routing strategy: Phi-5 for classification and low-stakes first passes, GPT-5.5 or Claude Opus 4.6 for reasoning-heavy work, the OpenAI o-series for long-horizon plans, and Claude Haiku 4.5 for high-volume tool-use. OST helps you design and tune the router so you do not pay frontier prices for simple answers.
Microsoft Entra Agent ID gives every AI agent its own non-human identity, separate from the person who created it. That means each agent has its own lifecycle, audit trail, and scoped permissions. You can deprovision an agent without touching the user. You can see an agent's activity in Defender for Copilot the same way you see a user's activity in Defender for Identity. OST configures Entra Agent ID as part of the managed cloud baseline so your tenant is ready before the first agent runs.
Four things, in order: audit SharePoint and OneDrive permissions for oversharing, deploy Microsoft Purview sensitivity labels with automatic labeling on high-risk content, configure DLP policies across Exchange, SharePoint, OneDrive, and Teams, and harden Entra Conditional Access for Copilot sessions. Then turn on Microsoft Defender for Copilot so prompt injections and policy violations show up in the same SOC queue. OST runs this as a five-part readiness assessment before any Copilot license activates, paired with our Copilot for Business service.
Prompt injection is blocked at the edge by Azure AI Content Safety and Prompt Shields, and at the application layer by input and output filtering aligned to the OWASP Top 10 for LLM Applications. Data leakage is contained through private endpoints on every Foundry dependency, scoped retrieval in Azure AI Search, and Purview labels that follow the data into and out of the model. Runaway spend is caught by FinOps guardrails: per-project token budgets, anomaly alerts, model-router policies that downshift to cheaper models where accuracy allows, and quarterly spend reviews that tie dollars to business outcomes.
