Not All Cloud CAD Is Equal: 10 Terms That Reveal the Difference

As cloud technology becomes increasingly prevalent across industries, the CAD space is no exception to this transformative shift.

With CAD vendors promoting their “cloud CAD software” solutions, understanding the terminology surrounding cloud computing is crucial to making informed decisions, because there’s a lot of “cloud-washing” happening. Cloud washing involves using the term “cloud” as a marketing buzzword rather than truly delivering the benefits and capabilities associated with cloud computing.

You might already be feeling the pressure from your CAD vendor to try their “cloud” offering or like you’re being forced into adopting their “cloud” version of CAD software. Even CAD experts who consider themselves “cloud-aware” can have trouble distinguishing between closely related terms that crop up in marketing materials or daily conversations.

We aim to clarify the top 10 cloud terms commonly used by CAD vendors while advocating that “cloud-native” CAD cloud systems are the gold standard.

But before exploring these terms, it’s essential to distinguish between software “built for” the cloud and those “retrofitted for” it. Legacy code and architecture present challenges for many CAD vendors, hindering their ability to leverage cloud benefits fully; therefore, some cloud CAD software solutions were retrofitted for the cloud. In contrast, cloud-native solutions were “built for” a cloud environment. As such, it delivers all the benefits of the cloud, from real-time collaboration to greater data security.

Not all “cloud” CAD software delivers every transformational benefit associated with the cloud. Some are limited by their architecture. Let’s explore 10 essential cloud terms you should know:

1. クラウドコンピューティングとは

まずは、基礎の基礎から始めましょう。クラウドとはいったい何でしょうか?クラウドとは、空を見上げたときに見える白いふわふわとしたもののほかに、ローカルサーバーやパーソナルコンピュータを使用する代わりに、インターネット経由でアクセスしてデータを保存、管理、処理するリモートサーバーのネットワークを指します。クラウドにより、ユーザーはインターネット接続があればどこでもアプリケーションやデータにアクセスできます。

So, rather than “downloading” software on a computer, users can access the software via the internet, and the software runs via the servers' cloud computing resource. This is one of the main advantages of cloud-based 3D CAD software over traditional software: There’s nothing to install, maintain, or update on your local machine. Cloud computing technology offers scalability, flexibility, and cost-effectiveness, as users can pay for only the resources they use and easily scale up or down as needed.

2. サービスとしてのソフトウェア (SaaS) とは

SaaS stands for Software-as-a-Service. It’s a cloud computing model where software applications are hosted and provided by a third-party provider over the internet for a subscription fee. Users access these applications via a web browser or mobile device rather than installing and maintaining them on their computers or servers. SaaS providers handle the maintenance, updates, security, and infrastructure, allowing users to focus on using the software rather than managing it. Common examples of SaaS software from CAD vendors are PTC’s Onshape and Creo, billed monthly.

3. What is Single-Tenant and Multi-Tenant?

Single-tenant architecture is a software hosting model where a single instance of an application or service serves a single customer. In contrast, a multi-tenant hosting model serves multiple customers. Multi-tenancy is commonly used in SaaS deployment models and provides the benefits of cost savings and scalability.

4. パブリッククラウドとは

A public cloud is defined as computing services offered by third-party providers over the public internet, making them available to anyone who wants to use or buy them. These services may be free or sold on demand, allowing customers to pay only for what they use.

Companies using a public cloud can access the applications they wish without the large upfront costs for hardware, software, or system maintenance.

5. プライベートクラウドとは

プライベートクラウドは、単一の企業または組織がアクセスして管理するオンサイトのコンピューティングアーキテクチャです。この戦略はメリットを享受できる顧客が 1 社だけなのでパブリッククラウドよりもコストがかかりますが、クライアントに合わせてリソースをカスタマイズできます。

Private clouds are best suited to companies that must meet regulatory requirements or deal with unusually sensitive data, such as financial data or health information. For manufacturers and engineering teams with strict IP protection requirements, a private cloud deployment of CAD cloud systems can offer tighter control over who accesses design data and how it's stored.

6. ハイブリッドクラウドとは

ハイブリッドクラウドは、パブリッククラウドとプライベートクラウドの両方の要素を組み合わせ、その間でデータやアプリケーションを共有できるコンピューティング環境です。ハイブリッドクラウドのセットアップでは、一部のリソースはサードパーティのクラウドサービスプロバイダーが管理するパブリッククラウド環境でホストされ、他のリソースはプライベートクラウド環境でホストされ、通常は組織の IT 部門が管理します。

7. クラウドストレージとは

Cloud storage is a service that allows users to store and access data over the internet on remote servers maintained by a cloud service provider. Instead of storing data on local storage devices like hard drives or flash drives, users can upload files to the cloud storage provider's servers, securely stored and accessed from anywhere with an internet connection. Dropbox, Google Drive, and Microsoft OneDrive are examples of cloud storage for individuals.

It’s important to note that cloud storage alone does not make a CAD platform “cloud CAD.” Storing files remotely while running the application locally is fundamentally different from a true cloud-native CAD experience.

8. クラウドホストとは

Cloud-hosted is a model in which a third-party cloud provider runs an application on its own servers on behalf of a customer. Cloud-hosted CAD software offers the flexibility and cost-efficiency of a rental business model. Instead of investing in and owning your software, hardware, and servers on-premises, you buy them as a service. Companies that choose cloud-hosted can quickly scale what they need or don’t need without incurring the large and ongoing investments required to run the applications on their own.

ただし、クラウドでホストされるサービスには仲介者 (および多くの場合ミドルウェア) が追加されます。CAD や PDM のソフトウェアの管理と更新は外部に委任できますが、コストがかかります。

9. クラウドベース、クラウド接続、クラウドパワードとは

これらの一般的な用語は、何らかの形でクラウドが関わっていることを示唆しますが、どの程度関わっているかを判断するのはユーザー次第です。アプリケーションをローカルハードウェアで実行するクラウドストレージモデルでしょうか?

多くのベンダーは、クラウドコンピューティングの特性や標準を真に満たしていなくても、クラウドコンピューティングへの注目や話題性に便乗し、"クラウドウォッシング"、つまり自社の製品、サービス、またはソリューションに "クラウドベース" または "クラウド対応" というラベルを付けてマーケティングを行っています。

This misleading marketing tactic can lead to confusion among consumers and businesses who may believe they are purchasing or using genuine cloud CAD solutions when, in fact, the product may simply be traditional software or services hosted on remote servers without the scalability, elasticity, or other benefits typically associated with true cloud computing. When evaluating any platform that claims to be cloud-based CAD, ask directly: Where does computation happen? Where is data stored? Can multiple users access and edit simultaneously without file check-out conflicts?

10. クラウドネイティブとは

クラウドネイティブとは、クラウドコンピューティングのすべての利点を最大限に活用するアプリケーションの設計、構築、実行を指します。スケーラビリティ、レジリエンス、自動化、継続的デリバリーの原則に重点を置いています。クラウドネイティブアーキテクチャにより、組織は優れたユーザーエクスペリエンスを提供しながら、より迅速にイノベーションを進め、市場の変化により効果的に対応できます。

With cloud-native CAD software, all data is stored on the cloud, and all required computation happens there. Nothing is downloaded or stored on a user's machine, and CAD files don’t exist in the traditional sense. Instead, data is stored in a centralized cloud database. Cloud-native architectures are optimized for reliability and eliminate crashes, data corruption, and data loss normally associated with CAD software.

Onshape: True Cloud-Native CAD Software

Onshape is the clearest real-world example of cloud-native CAD in action. Built from scratch for the cloud, with no desktop version, no local file system, and no installer, Onshape demonstrates what's possible when CAD software is designed entirely around cloud infrastructure rather than retrofitted for it. Every save, every version, every collaborator edit happens in the cloud, automatically.

Collaboration is a standout advantage of cloud-native CAD software. Engineers and designers can work on the same model simultaneously, in real time, from any location without the friction of checking files in and out or reconciling conflicting versions. For global manufacturing and engineering teams, this means faster design cycles and fewer bottlenecks.

Security is another key consideration. Cloud-native CAD platforms typically benefit from enterprise-grade security infrastructure, including encryption at rest and in transit, role-based access controls, and audit trails, often exceeding what most in-house IT environments can provide. Your IP stays protected without sacrificing accessibility.

For manufacturing teams specifically, the benefits of a cloud-native manufacturing platform extend beyond CAD with integrated PLM, real-time BOM management, and seamless supplier collaboration all become possible within a single, always-updated environment, including PDM built in by design, not added as a separate tool.

ゴールドスタンダードとしてのクラウドネイティブ

Now that we've clarified these essential cloud CAD terms, why are cloud-native architectures considered the gold standard?

A cloud-native architecture is the best because it is specifically tailored to harness the full potential of cloud computing – and now AI development – since it was designed for a cloud environment.

By embracing microservices, containers, and serverless computing, cloud-native CAD software enables organizations to achieve unprecedented agility, scalability, and reliability. With cloud-native approaches, businesses can innovate quickly and rapidly adapt to changing market conditions while delivering exceptional value to their customers.

Moreover, cloud-native architectures promote a culture of continuous improvement and innovation. By embracing DevOps agile practices and automation, organizations can streamline their development and deployment pipelines, reducing time-to-market and accelerating innovation cycles.
