Accelerate Your SaaS Development and Performance with Cloud Volumes ONTAP

Software-as-a-service, or SaaS, development has accelerated to a dizzying pace. This is mostly due to the cloud, which makes it possible for SaaS developers to easily spin up resources on demand to test and roll out new features for their users. However, cloud deployment for SaaS applications comes with its own set of challenges—namely, maintaining SLAs, and designing for high availability, resiliency, and storage efficiency.

How can you ensure your SaaS overcomes these challenges? The pace of SaaS development and delivery in the cloud depends to a great extent on the underlying storage layer. Cloud Volumes ONTAP delivers an enterprise-class data management solution that runs AWS, Azure, or Google Cloud block storage disks, making it possible to meet the high-performance storage demands of SaaS-based applications while significantly cutting time to market.

In this blog we will explore some of the challenges faced by organizations while building SaaS applications and how Cloud Volumes ONTAP as a storage solution helps address them.

SaaS Development in the Cloud: Key Considerations

What customers look for in a SaaS application is reliability, high responsiveness, security, and value for money. To deliver on this expectation while ensuring ROI, the underlying infrastructure for SaaS-based applications—especially the storage layer—should be reliable and highly available while still being easy to manage and operate.

There are some key factors that determine the success of SaaS software development in the cloud. The most important aspect is ensuring that the application ecosystem is robust to honor the SLAs. Applications should be highly available and resilient from any kind of planned or unplanned cloud outages. Additionally, as the user base grows, the storage should be scalable on the fly to meet the increased demand while being cost effective in the process. All these should be achieved without compromising on the application performance. Any snags or delays in accessing the application could negatively impact the user experience.

The faster you can release features to your customers, the more successful your application will be. Agile development cycles demand highly flexible storage systems that are available on demand. Setting up the infrastructure shouldn’t become a bottleneck during any phase of developing and shipping the application. If a new feature demands new environments to be created for the process of “rinse, repeat” before the delivery, your cloud storage solution should be agile enough to support that requirement. Reduced time to market means happy customer base and increased profits.

Choosing the Right Storage for your SaaS Applications

Storage is an integral component of your SaaS application architecture in the cloud. It can make or break the efficiency of your SaaS development. Any bottleneck at the storage layer will act as a success inhibitor in the SaaS development process. Let’s look into some of the desired characteristics to be taken into consideration to avoid the common pitfalls while selecting a storage solution for your SaaS applications in the cloud.

High availability: SaaS applications are bound by SLA commitments, often very stringent ones, like 99.999% availability. That means the high availability of cloud storage used by the application is non-negotiable. The storage your SaaS uses should be capable of overcoming both data center and regional cloud outages. In the event of a failure, seamless failover and failback should be supported by the storage so that users will be able to access the application as if nothing was wrong.

Data protection: A SaaS’s storage service should be capable of protecting the application from unexpected data loss and corruption. Additionally, disaster recovery is another key consideration. Application-aware, point-in-time backup and recovery is crucial here. The data protection and DR should be planned to adhere to agreed RPO and RTO. Ease of failing back after recovering from a disaster is another deciding factor for the storage. The storage service should also have the capability to support non-disruptive testing of your recovery strategy for the SaaS application.

Performance: There is a general misconception that cloud storage solutions are not as good as their on-premises counterparts. However, with the right performance planning for the SaaS application and mapping against available cloud storage SKUs, high-performing cloud-based storage can easily be achieved. The location of the service, size, the tiers/SKU, and throughput offered by the storage are some of the factors to be taken into consideration along with the tradeoff between cost and performance. 

Agility: Faster time to market is a key differentiator for a SaaS-driven business. The underlying storage solution should be agile to meet demands of fast-moving SaaS development where dev/test environments should be spined up on the go before rolling out new features. This should also be achieved without significant cost overhead. However, this can be a challenge as the high number of test copies—sometimes hundreds per automated test cycle—can drive up storage costs and take considerable amounts of time to create.

Storage efficiency: Cloud storage uses a pay-as-you-go model. The more cloud resources you consume, the higher your total costs of operation. Storage sprawl can burn a hole in your monthly cloud bill and eat into the SaaS application profit. While storage should be agile to support fast-paced application development, it should also be efficient to keep costs in check. Cloud service providers deliver low-cost storage solutions like cold and archive tiers for object storage that should be effectively leveraged to bring in storage efficiency. However, tiering from block storage to object storage is not natively available in leading cloud platforms and might need specialized solutions.

Data migration: SaaS applications may not always be born in the cloud. Seamless migration of existing data from on-premises deployments to the cloud is another desired feature of the storage ecosystem. Most often, the migration process will be done in stages, starting with non-live DR and backup data to test the waters. The storage solution should also help avoid vendor lock-in once the data is migrated to the cloud and hence should align with your planned exit strategy.

Security: When data is moved to cloud, you need to ensure that data is as protected as it was on-premises. Security of the data during a migration, i.e., in transit, and at rest once it is moved to cloud should be taken into account. The right cloud storage solution should also support the data privacy and compliance requirements of your SaaS application. For example, having built-in ransomware protection to prevent data theft is a desirable feature.
