Cloud isn't as risky as you think. Enterprises are migrating mission- critical apps to the cloud and still thriving, proving it can be done. Mission-critical application providers — like Oracle, SAP, Salesforce, and others — have invested in software-as-a-service (SaaS) offerings, and companies are buying. But you’re still responsible if the mission-critical app goes down, no matter where it runs. If you already use third-party apps on-premises and you’re considering switching to SaaS, look closely at the vendor’s reliability history as compared with your own. If your mission-critical app is proprietary, high migration costs may make the risk question moot: Switching to a third-party SaaS solution might be your best bet. And if you’re constrained by law or regulation, that may limit your options. If you’re considering infrastructure-as-a-service (IaaS) or platform-as-a-service (PaaS), then you still control those cloud-based components and you benefi t from the agility, resiliency, and safeguards that are (or should be) the provider’s value-add. Ultimately, migrating mission-critical software or resources to the cloud is a cost vs. risk vs. opportunity decision unique to every business.
