Cadence announced CloudBurst in 2019 as a managed cloud environment for semiconductor and electronic-systems design teams that needed ready-to-use EDA tools and extra compute alongside their own data center. Cadence’s current public materials use the names True Hybrid Cloud and Managed Cloud Service. The available sources do not establish whether CloudBurst is still separately orderable or was formally renamed, so it is best understood as a historically announced platform rather than a confirmed current product.
What was Cadence CloudBurst?
CloudBurst was Cadence’s 2019 offering for running compute-intensive electronic design automation (EDA) work in the cloud. Cadence described it as a complement to a customer’s on-premises data center: teams could access pre-installed Cadence tools through a browser and use additional cloud compute when project demands exceeded local capacity. The announcement named AWS and Microsoft Azure as deployment environments. Cadence’s April 1, 2019 announcement described functional verification, circuit simulation, library characterization, and signoff as supported work.
The intended audience was design teams dealing with large design files and jobs that could benefit from more compute. Cadence said customers could use the service without first building their own cloud environment. Its launch announcement claimed a deployment could be ready in a day or two after purchase; that was a 2019 vendor statement, not a current service commitment.
Two historical deployment models
Cadence’s 2022 retrospective described two CloudBurst models: a full SaaS environment managed end-to-end by Cadence, and a platform SaaS model built on a customer’s existing AWS or Azure setup. This is historical context; it does not confirm that either model is currently sold under the CloudBurst name.
How the hybrid approach works
In the hybrid model described in Cadence’s 2025 True Hybrid Cloud brochure, jobs are submitted to an on-premises high-performance computing (HPC) cluster first. Orchestration checks local capacity and can route work to cloud compute when local resources are insufficient. The approach is designed to coordinate workloads across clusters and sites, manage data caching or replication, and synchronize results back to on-premises systems.
Cadence says the system aims to move only the design data needed for a job, limiting network transfers and cloud storage needs. Its brochure gives a typical figure of about 10% of required design files transferred. That is a Cadence-published generalization, not an independent benchmark or a guarantee for a particular workload. Cadence describes the goal as making job location transparent to the user: “the user doesn’t need to worry about where the job is being launched.”
In practical terms, engineers can keep using familiar EDA and HPC workflows while orchestration uses local capacity first and cloud resources for overflow. Whether that works well depends on the team’s workload parallelism, storage and network design, software licenses, cloud costs, and foundry or security requirements. Those factors need to be checked against the actual design flow.

Cadence’s current public materials distinguish several cloud deployment approaches. The names and descriptions below reflect Cadence’s public-facing material; they do not establish that CloudBurst was formally renamed.
| Offering | Who manages the cloud environment | How it is positioned |
|---|---|---|
| True Hybrid Cloud | Presented as technology for Cadence Managed Cloud Service; the brochure describes orchestration between on-premises and cloud compute. | EDA-optimized hybrid deployment with workload bursting and managed data movement. Cadence brochure |
| Managed Cloud Service | Cadence describes a turnkey managed environment with pre-installed tools and license management. | Cloud environment for design, verification, and implementation. Cadence service page |
| Cloud Passport | The customer uses its own public-cloud account and remains responsible for setting up and supporting the environment. | Customer-managed use of Cadence cloud-ready tools. Cadence lists AWS, Microsoft Azure, Google Cloud Platform, and IBM Cloud among providers used by customers. Cadence Cloud Passport page |
Cadence’s current cloud brochure reports more than 300 customer tapeouts and more than 150 companies served. These are Cadence portfolio claims, not independently audited performance statistics. Cadence cloud brochure
How to evaluate a cloud setup for an EDA team
The right arrangement depends less on the label than on who will operate it and how well it fits the team’s existing design flow. Before selecting a model, assess these areas with Cadence and your internal infrastructure, security, and design teams:
- Operations: Establish who configures and supports cloud infrastructure, CAD tools, storage, and user access.
- Capacity needs: Decide whether the goal is to run full design flows in a managed cloud or add overflow capacity to an on-premises cluster.
- Workflow fit: Confirm compatibility with job schedulers, EDA licenses, PDKs, and foundry processes.
- Data movement: Understand how files are transferred, cached, replicated, and synchronized—and how that affects network performance and storage.
- Security and location: Check data protection, cloud-region availability, foundry rules, and contractual requirements for the specific project.
- Cost: Compare variable cloud operating expense with the cost and utilization of on-premises capacity. The cited Cadence sources do not provide comparative pricing; ask for a customer-specific quote and configuration.
Cadence’s 2019 launch announcement quoted its president, Dr. Anirudh Devgan, calling the offering “an unparalleled offering for hybrid cloud environments.” That was a company statement at launch, not an independent assessment. The same announcement quoted a customer reporting a 10X productivity improvement in one tapeout case; it is a customer-reported result for that case, not a general platform benchmark. The available material does not provide independent performance testing or a comparative pricing study.

Is Cadence CloudBurst still available?
The reviewed Cadence sources do not establish that CloudBurst remains a separately orderable product, nor do they say it was formally renamed. Cadence’s current public terminology instead features True Hybrid Cloud, Managed Cloud Service, and Cloud Passport. Treat CloudBurst as a historical product name unless Cadence confirms its current status directly. For a present-day evaluation, verify availability, supported cloud regions, licensing, service scope, data protections, pricing, and contract terms with Cadence.
