In case you are not fully aware of the possible pitfalls that can occur during SaaS application development and maintenance, here’s the truth: this is uncharted territory you can easily get into, so gear up with some insights we’ve prepared. Full story here.
Zero Downtimes & Easy Updates
Bugs and security breaches are a big concern for software developers, as they can significantly impact the way everything worlds. A potential issue can lead to credibility loss, productivity reduction, and reduced revenue. However, SaaS solutions can mitigate all these risks due to these benefits:
- Blue-green deployment: when two identical environments (blue and green) are run, so that, for instance, a new code can be tested without disrupting the users’ digital sessions.
- Rolling updates: when the app is being gradually updated across servers while remaining available for users.
- Load balancing: if there is a server outage, another server will take over through traffic distribution.
Also, developers frequently use various strategies to comply with industry regulations and ensure seamless access to the SaaS solution:
- CI / CD;
- Breaking down the application into microservices;
- Using feature toggles;
- Backward-compatible updates.
All in all, creating a sustainable balance between easy updates and their deployment to end-users without any disarrays is a prerequisite to the SaaS app's impeccable quality.
Hybrid Infrastructure
Another prerequisite will be a setup where on-premises systems, private clouds, and public clouds are combined. This invariably brings about a number of brainteasers for the developers:
- Integration complexity issues coupled with compatibility issues;
- Ensuring consistent security standards across multiple environments;
- Data migration and distribution;
- Centralized monitoring;
- Complex diagnosing issues;
- Balancing the workload between on-premises and cloud environments;
- Managing costs across a multiple environment;
- Implementing DevOps practices.
Despite seeming complex, the multiple environments challenge can be effectively responded to by some tools like:
- Hybrid cloud management platforms;
- Centralized monitoring, security, and data management solutions;
- Standardizing deployment processes;
- Coherent policies for data management and security.
Hybrid infrastructure challenges can be managed with the help of meticulous planning and advanced tools. As it stands, multiple environment’s values definitely outdo its transient toughies.
SaaS Scalability
Scalability is among key requirements in SaaS development, and it’s about how efficiently a SaaS application can manage the multiplying numbers of new users, data volume, and erratic usage patterns. If not predicted, prevented or securely fixed, these issues will directly lead to such app’s malfunctions as:
- Downtime and latency;
- Ineffective data distribution;
- Negative impact of one tenant’s activities upon others (for apps with multi-tenant architecture);
- Over- and under-provisioning of resources;
- Poor management of inter-service communication, data consistency, and service discovery;
- Inadequate load balance.
With a productive set of optimization strategies and advanced cloud-native technologies, scalability challenges can be successfully overcome. Here are some of the alternative approaches:
- Leveraging cloud services to cope with fluctuating loads;
- Allowing individual components of the application to scale independently by adopting a microservices architecture;
- Implementing database sharding and partitioning;
- Using automated scaling mechanisms and load balancers;
- Multi-tenancy optimization through effective tenant isolation;
- Tracking performance metrics, usage patterns, and resource consumption with monitoring tools.
Responding to scalability challenges is multifaceted and intricate. Nonetheless, it is a crucial measure that will yield seamless and, consequently, unrivaled customer experiences.
