Azure Container Apps Dynamic Sessions vs E2B
Azure's Hyper-V-isolated sessions for running LLM-generated code, from prewarmed pools, as a built-in code interpreter or your own container. For teams building agents on Azure. Azure Container Apps Dynamic Sessions does not publish comparable vCPU and memory rates, so no hourly price is compared; E2B lists $0.166 an hour for a 2 vCPU / 4 GiB sandbox.

Prices are list prices for one hour of a 2 vCPU / 4 GiB sandbox: 2 × the vCPU rate + 4 × the memory rate. Each value links to the page it came from; not published means the vendor states no figure. How we compare.
Pick Azure Container Apps Dynamic Sessions instead of E2B when
- your stack already runs on that cloud: Azure Container Apps Dynamic Sessions is a first-party service there, so identity, billing and networking stay in one place.
Stay on E2B when
- pause has to keep running memory as well as files: E2B's pause saves both, and Azure Container Apps Dynamic Sessions does not state memory state in our data.
- you need a SOC 2 report: E2B states Type II, and Azure Container Apps Dynamic Sessions states none in our data.
- you want managed cloud, your own cloud account and self-hosting from one vendor: E2B offers all three, with BYOC on its Enterprise plan.
All Azure Container Apps Dynamic Sessions facts
Source per value- Isolation Isolation technology the vendor states for each sandbox.
- Hyper-V 1
- Other isolation options Alternative runtimes the vendor offers besides the default (e.g. VM runtime, gVisor for GPU).
- Code interpreter pools or custom container pools 1
- Deployment Managed cloud service, self-hosted software, or both.
- managed 1
- Billing basis What the meter counts: wall-clock allocated resources, active CPU only, requests/plan quota, session-hours, or free software.
- session-hour 1
- vCPU price $/vCPU-hr Published on-demand CPU rate normalised to USD per vCPU-hour (per-second rates multiplied by 3,600; per-core rates divided by vCPUs per core where the vendor defines it). Lowest public tier, default region. 0 means the vendor states no separate CPU charge.
- Not published
- Memory price $/GiB-hr Published memory rate normalised to USD per GiB-hour (GB treated as GiB where the vendor does not distinguish). 0 means the vendor states memory is free.
- Not published
- Sandbox from $/sandbox-hr Smallest published per-sandbox hourly price, where the vendor publishes one.
- $0.03 3
- Paid plan from $/mo Cheapest paid platform plan fee (before usage).
- Not published

- Persistence / snapshots Filesystem state can be kept between runs (snapshots, persistent disks, volumes).
- Not published
- Pause / resume A sandbox can be paused, suspended, hibernated or put in standby and resumed later.
- Not published
- Memory state kept Pause/hibernate preserves running memory state, not only the filesystem.

- 2 vCPU + 4 GiB per hour $/hr Hourly list price of one 2 vCPU / 4 GiB sandbox: 2 x the vCPU rate + 4 x the memory rate, from the two published rates. Left empty for self-hosted software and for vendors without both rates. Vendors that bill CPU only while busy (Vercel, Cloudflare, Upstash, Tensorlake, AWS AgentCore) cost less for idle agents than this shows.
