In the ever-evolving realm of software development, the term "cloud-native computing" has risen to prominence as a guiding philosophy for software developers. It encompasses a distinct set of practices and principles that differentiate cloud-native software development companies from their traditional counterparts. In this exploration, we will delve into the core aspects that set these companies apart and the advantages they offer in today's digital landscape
Cloud-Native Definition
Cloud-native represents a revolutionary approach to conceiving and managing software applications. It leverages the inherent flexibility, scalability, and resilience of cloud computing. Cloud-native development focuses on harnessing a range of tools and techniques that cater specifically to constructing applications within the public cloud environment, a stark contrast to traditional architectures designed for on-premises data centers.
The origins of the cloud-native philosophy can be traced back to visionary companies often referred to as "born in the cloud" enterprises. Notable examples include industry giants like Netflix, Spotify, Uber, and Airbnb. These pioneers blazed a trail toward digital agility and disruptive competitive advantage through the adoption of cloud-native practices.
The Cloud Native Computing Foundation (CNCF) provides a more precise perspective, emphasizing application containerization. This involves breaking down applications into microservices and packaging them in lightweight containers for deployment and orchestration across diverse servers.
In the CNCF's own words: "Cloud-native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds."
Cloud-native software development companies incorporate a holistic approach, uniting microservices, cloud platforms, containers, Kubernetes, immutable infrastructure, declarative APIs, and continuous delivery techniques with agile methodologies and the principles of devops.
Cloud-Native Landscape
The transition towards cloud-native practices has given rise to an expansive landscape of predominantly open-source tools. The CNCF curates an interactive graphic illustrating this burgeoning ecosystem.
To comprehend the distinctive characteristics of cloud-native software development companies, it is essential to grasp the four fundamental layers within cloud-native computing:
1. The Application Definition and Development Layer: Positioned at the top of the cloud-native stack, this layer focuses on the tools essential for developers to construct applications. These include databases, messaging systems, container images, and continuous integration and continuous delivery (CI/CD) pipelines.
2. The Provisioning Layer: This layer deals with everything necessary to construct and secure the environment in which an application operates. In the cloud-native realm, this entails treating infrastructure as code, storing images in repositories, automating builds, and addressing security requirements through vulnerability scanning, key and policy management, and authentication tools.
3. The Runtime Layer: This layer is concerned with all aspects related to the execution of cloud-native applications, encompassing container runtimes (commonly Docker), storage, and networking.
4. The Orchestration and Management Layer: This critical layer amalgamates the tools required for deploying, managing, and scaling containerized applications. It often features Kubernetes, alongside components like service discovery, service proxy, API gateway, and service mesh.
In addition to these layers, it is crucial to emphasize the implementation of observability practices to ensure effective monitoring of these services. Some organizations opt to streamline their entire stack into a self-service internal developer platform or choose opinionated platform-as-a-service (PaaS) solutions from vendors to facilitate adoption for their development teams.
### What Sets Cloud Native Software Development Companies Apart
Cloud-native software development companies differentiate themselves through their distinct approach to architecture and development, deviating significantly from traditional enterprise applications, typically tailored for on-premises data centers. Here are key distinctions that underscore what sets them apart:
1. Languages: Unlike on-premises applications, which often rely on traditional languages like C/C++, C#, and enterprise Java, cloud-native apps gravitate towards web-centric languages such as HTML, CSS, Java, JavaScript, .NET, Go, Node.js, PHP, Python, and Ruby. This choice attracts top engineering talent.
2. Updatability: Cloud-native applications are engineered for high availability, resilience, and regular updates, in stark contrast to on-premises applications that follow a slower, once or twice a year update cycle using a waterfall methodology. Cloud-native practices foster higher development team productivity, enabling them to focus on competitive advantages and deliver new features more frequently.
3. Elasticity: Cloud-native applications seamlessly adapt to cloud elasticity, adjusting resource consumption based on demand. In contrast, on-premises applications necessitate the physical provisioning of additional infrastructure for effective scalability. Cloud-native practices also offer cost advantages, allowing organizations to pay for actual usage and avoid overprovisioning.
4. Multitenancy: Cloud-native applications are designed to function efficiently in virtualized environments, easily sharing resources with other applications through a multitenant model, fostering greater development team efficiency.
5. Downtime: Cloud-native applications benefit from the enhanced redundancy offered by hyperscale cloud vendors, minimizing outages by swiftly redirecting traffic to alternative regions, thereby avoiding costly downtime.
6. Automation: Cloud-native practices present numerous automation opportunities for engineers, enabling them to build solutions once and shift their focus to more pressing challenges.
7. Stateless: Cloud-native applications tend to adopt a stateless model, avoiding the persistence of data between sessions. This approach simplifies scaling across multiple servers, improves performance through caching, reduces storage requirements, and mitigates vendor lock-in concerns.
Embracing Cloud-Native Principles
Despite the evident advantages, transitioning to cloud-native software development practices can present challenges. Attempting to migrate existing on-premises applications to a cloud-native paradigm without addressing architectural considerations is a common misstep. Rearchitecting applications for the cloud poses significant engineering challenges, necessitating a mix of the right skills, adaptation to cloud-centric security models, and the management of evolving cost dynamics.
Nonetheless, software developers and organizations should wholeheartedly embrace cloud-native principles as a foundational organizational philosophy. This can manifest in the development of new cloud-native applications or the decomposition of existing monolithic applications into microservices to better align with the cloud-native environment.
This shift mandates a transition from traditional waterfall deployment models to more agile development principles such as minimum viable product (MVP) development, a culture of automation, multivariate testing, rapid iteration, observability, and close collaboration between development and operations teams within a devops framework.
In summary, what sets cloud-native software development companies apart is their unwavering commitment to innovation, agility, and efficiency in the digital age. Their embrace of modern languages, regular updates, elastic scaling, multitenancy, minimal downtime, automation, and stateless architecture positions them as the vanguards of contemporary software development. As organizations seek to thrive in the ever-changing technology landscape, choosing a cloud-native software development company like Activelobby is the strategic choice for building a digital future.
