Building resilience in cloud: Strategies, advantages, and considerations

Cloud resilience

When it comes to cloud computing, resilience is an infrastructure's ability to bounce back from setbacks seamlessly, ensuring uninterrupted operations in the face of outages, malfunctions, software bugs, and even natural disasters. We'll explore measures you can take to enhance resilience in your cloud, plus discuss the advantages and limitations of building a resilient cloud system.

Embracing redundancy through multiple servers or data centers is one of the key resilience-building strategies. This ensures that even if one component fails, the system can continue functioning without an outage or failure. Load balancers like AWS ELB or Azure ALB helps in distributing traffic across multiple servers, therefore preventing any single server from being overloaded.

Barriers to achieving cloud resilience

  1. Cost: Enhancing resilience can be costly, involving expenses such as additional hardware or services and the development and testing of disaster recovery plans. An organization may want to invest in a cloud cost management tool to check its rising cloud costs.

  1. Complexity: Establishing a durable cloud system requires coordination among multiple teams and the incorporation of various technologies and procedures, making it a challenging task.

  1. Limited control: Users may have limited control over the underlying infrastructure, and depending on the type of cloud service used, this can affect their ability to adopt certain resiliency measures.

  1. Unforeseen problems: Consider a case where power outages frequently happen in an availability area. This will lead to increased cost due to investment in power backup systems and interruptions in server uptime.

Strategies for improving cloud resilience

  1. Backup and recovery systems: Investing in strong backup and recovery systems makes your ecosystem safe and resilient in the event of a disaster. Having robust backup systems also ensures the business is not at loss during disasters.  

  1. Leverage monitoring and alerting tools: Monitoring tools help identify issues before they escalate, and their alerting systems notify relevant personnel promptly for proactive issue resolution.

  1. Implement security best practices: Encryption and access controls help ensure security compliance across data and systems, protecting them from unauthorized access and potential breaches.

  1. Build chaos engineering teams: The practice of intentionally injecting bugs into a system to test its resilience and prepare for worst is a proactive step organizations can take in their fight against cloud failure. By building such a team, admins can identify potential failure points and correct them before an actual outage happens.

Resilient cloud systems can scale up or down as needed, adapting to changing requirements and workloads. Here are some advantages that cloud resilience offers when adopted as a practice.

  1. Greater availability: The mean time to repair (MTTR) is vastly reduced, giving users higher cloud availability. Services like AWS Resilience Hub allows you to track the resilience of your applications.

  2. Increased security: Resilient systems lead to a secure ecosystem that can quickly recover from major security breaches, contributing to better compliance. Site24x7's Guidance Report offers best practices for security and compliance in your cloud services.

  1. Cost savings: Reduce costs associated with disruptions, including lost revenue, repair expenses, and reputation damage through a native or a third-party cloud cost management tool.

  1. Improved decision-making: Data-driven decision-making is facilitated through a resilient system, and it cannot be disrupted by external factors like outages.


While building resilience in the cloud comes with its set of challenges, the benefits are clear. With Site24x7, you can implement strategic measures that not only ensure seamless operations but also contribute to cost savings, increased competitiveness, and improved overall system reliability. Site24x7 allows you to create a resilient cloud infrastructure that can withstand any challenge you face with your cloud services.
