Unlocking the Cloud: Embracing Cloud-Native Architecture – Part 3
What is cloud-native architecture?
This is the last of our blog series where previous we explored cloud migration challenges, and benefits of cloud migration. This post will focus on what is cloud-native architecture?
Cloud-native architecture is an approach to designing and developing applications that are optimised for the cloud environment. Cloud-native applications are built using microservices, containers, orchestration, and other cloud-based technologies that enable them to be scalable, flexible, resilient, and portable across different cloud platforms and services. Cloud-native applications can also leverage the cloud’s automation, monitoring, and security capabilities to improve their performance, reliability, and security.
When referring to cloud-native, I also mean cloud-agnostic, where architecture aims to run seamlessly across any cloud provider. Cloud-native is sometimes referred to as services that are dependent on a single cloud platform, but in this blog, I will be very vendor-agnostic.
Some of the benefits of cloud-native architecture are:
– Scalability: Cloud-native applications can scale up or down their resources and services according to the changing needs and demands of the users and the business. This can help improve performance, availability, and customer satisfaction, as well as reduce costs and waste.
– Flexibility: Cloud-native applications can access and use different cloud platforms and services that suit their requirements and goals. This can help enhance productivity, collaboration, and innovation, as well as enable new business opportunities and models.
– Resilience: Cloud-native applications can manage failures and errors gracefully without affecting the overall functionality and user experience. This can help ensure continuity, quality, and trustworthiness of the applications.
– Portability: Cloud-native applications can run on any cloud platform or service without requiring significant changes or modifications. This can help avoid vendor lock-in, reduce dependency, and increase agility and competitiveness.
Some of the challenges of cloud-native architecture are:
– Complexity: Cloud-native applications involve multiple components and technologies that need to be designed, developed, tested, deployed, and managed in a coordinated and consistent manner. This can increase the complexity and difficulty of the application lifecycle management.
– Skills gap: Cloud-native applications require new skills and competencies that may not be available or sufficient in the existing workforce. This can create a skills gap that needs to be filled by hiring, training, or outsourcing.
– Security risks: Cloud-native applications introduce new security risks that need to be addressed and mitigated. For example, data may be exposed or compromised during the transfer or storage in the cloud, or unauthorised access may occur due to misconfiguration or weak authentication. Moreover, different cloud platforms and services may have different security standards and policies that need to be followed.
