Many modern AI and automation platforms can be delivered in two ways: as a managed SaaS product, or deployed inside a customer’s own cloud environment. These options can look similar on the surface because the features and user experience may be nearly identical. The real differences show up in where the platform runs, how it connects to your systems, and how much control you want over infrastructure and change management.

Squid supports both deployment models, so you can choose the option that best fits your security requirements, infrastructure strategy, and time-to-value goals.

This post breaks down SaaS vs VPC deployment at a high level, with practical tradeoffs to help you choose the right model for your organization.

The Two Options at a Glance

There is one core question that drives everything else:

Where does the platform run?

SaaS Deployment

In a SaaS model, the platform runs in the vendor’s cloud environment. The vendor operates and maintains the infrastructure, handles upgrades, and provides access to the product as a managed service.

To connect the platform to your internal systems, you typically configure connectors and grant controlled access from your environment to the vendor’s environment. The vendor’s platform then reaches your data sources and services through that approved access path.

Your data remains isolated to your organization. Modern SaaS architectures enforce strict tenant isolation so that one customer’s data is never accessible to another customer.

In Squid AI, your data is accessed through connectors and is used only to perform the workflows or automations that you configure. Data is never shared across customers or used to train underlying models without explicit permission.

VPC Deployment

In a VPC model, the platform is deployed inside your cloud environment, typically within your own virtual private cloud. Instead of the vendor’s platform reaching into your network from the outside, the platform runs within your network boundary and accesses data locally.

This approach is often described as “bring your own cloud” or “deploy to your account,” because the infrastructure lives under your cloud ownership and controls.

Because the infrastructure runs in your account, your organization retains full control over how data is accessed, stored, and governed. This model is often preferred when strict security, compliance, or data residency requirements apply.

SaaS Deployment: Pros and Cons

Pros

**Fastest time to value
**Because the platform is already running, teams can often get started immediately. In many cases, it is a matter of creating an application, configuring connectors, and beginning to build workflows or agents within minutes

**Lowest operational overhead
**The vendor manages infrastructure, scaling, reliability, and day to day operations. Your team does not need to provision environments or run deployment projects to get the platform live.

**Automatic access to the latest improvements
**SaaS offerings are typically upgraded continuously. Customers benefit from new capabilities, performance improvements, and fixes without needing to schedule or execute upgrades themselves

Cons

**Requires controlled external connectivity
**Because the platform runs outside your network, you will need to allow your environment to expose approved access to the vendor’s platform for the systems you want to connect. For organizations with strict security or compliance policies, this requirement can be a blocker

**Less infrastructure control
**In a SaaS model, the vendor owns and operates the runtime environment. While mature SaaS products offer strong security and governance controls, your organization has less direct control than it would with a deployment in your own cloud account.

VPC Deployment: Pros and Cons

Pros

**Stronger alignment with strict security and compliance postures
**When the platform runs inside your network boundary, the platform can access your internal systems without requiring external third party network access. This is often better aligned with policies that restrict exposing sensitive systems outside the organization.

**More control over environment and change management
**Because the platform is deployed into your cloud environment, you control infrastructure boundaries and can align operations with internal processes. Many organizations prefer this for governance, auditing, and controlled rollout practices.

**Local proximity to internal systems
**In practice, placing the platform closer to data can simplify access patterns for certain architectures, since traffic stays within your cloud environment rather than traversing to an external vendor environment.

Cons

Deployment and upgrades require deliberate effort

VPC deployment is a project, not a toggle. Initial setup typically involves provisioning infrastructure, establishing permissions, passing security reviews, and coordinating with internal teams before the platform can go live. Once deployed, upgrades are intentional rather than continuous, meaning organizations may adopt new capabilities more slowly than with a SaaS model.

**Infrastructure costs sit in your cloud account
**When the platform runs in your VPC, the underlying cloud resources are provisioned in your account. This typically includes compute, storage, networking, and any managed services the platform depends on. Depending on usage and scale, these infrastructure costs can become a significant expense. In a SaaS model, these costs are bundled into the service fee and managed by the vendor.

Which Deployment Model Should You Pick?

A useful way to decide is to start with constraints, then optimize for speed.

Choose SaaS if:

• You want the fastest path to production.

• You prefer minimal infrastructure ownership and operational overhead.

• Your security policies allow controlled external access to the systems you want the platform to connect to.

• You want to be on the latest version automatically.

Choose VPC if:

• Your security or compliance posture requires the platform to run inside your cloud environment.

• You need tighter control over network boundaries and access patterns.

• Your organization prefers deliberate upgrades aligned to internal change management processes.

• You want all platform infrastructure and data processing to remain inside your cloud account.

• You are willing to trade speed and simplicity for control.

In most organizations, SaaS is the default because it is faster to evaluate, faster to deploy, and easier to operate. Even with SaaS, when you use Squid AI, your data remains isolated to your organization through tenant-level security controls. VPC is a strong fit when compliance requirements, policy constraints, or architecture standards make an in-account deployment necessary.

How Squid AI Supports Both Options

If speed is the priority, Squid can run as a managed SaaS platform. Teams can create an application, configure connectors, and begin building agents quickly without running an infrastructure project.

If tighter network control is required, Squid can be deployed directly inside your VPC. In this model, agents run within your cloud environment and access internal systems locally without requiring external third-party network access.

Some organizations also take a hybrid path. They begin with SaaS to validate the platform quickly, then migrate to a VPC deployment once the solution is ready to operationalize at scale. Squid supports this transition, so teams do not have to commit to one deployment model permanently at the start.
