Wat is cloud-native architectuur?

Cloud-native architectuur is een gespecialiseerde ontwerpbenadering voor het bouwen en uitvoeren van applicaties binnen cloudcomputingomgevingen. Deze benadering benut als gevolg daarvan de inherente kenmerken van de cloud, zoals schaalbaarheid, elasticiteit of zelfs veerkracht, ten koste van de potentiële controle over bronnen en flexibiliteit.

Cloud-native applications are designed to incorporate features that facilitate their performance in volatile cloud environments, including rapid response capabilities and adaptability to change. 

Adapting monolithic applications is not entirely feasible, as the process may require rewriting the entire structure as a result of the nature of the concept for cloud environments. In contrast, cloud-native architecture, encompassing microservices, is often considered a more suitable approach for modern requirements than traditional architecture.

The main difference between cloud-native and monolithic architecture is in how they are structured. Mono applications are designed where all the elements are integrated, while cloud-native applications are divided into microservices of loosely connected services. This method is characterized by its decentralized nature, where services can be independently designed, provisioned, and scaled, potentially resulting in greater adaptability, efficient resource utilization, and a decentralized architecture.

The use of cloud-native architecture can also have effects on the company’s scalability, flexibility, and expenditure model.

• Schaalbaarheid: Macro applications made from microservices can also scale out by adding or willfully removing instances of distinct services depending on the workloads.
• Resilience: Cloud-native applications use ‘isolation’ and self-healing to minimize or prevent downtime in failure cases.
• Agility: Cloud-native applicaties bestaan meestal uit microservices die hun ontwikkeling en implementatie mogelijk maken.
•  Betalen per gebruik: In cloud-native architectuur kunnen organisaties de toewijzing van resources aanpassen op basis van het werkelijke gebruik, wat mogelijk gevolgen heeft voor kostenoptimalisatie.

Er zijn verschillende technologieën die essentieel zijn voor cloud-native ontwikkeling.

• Microservices: Toepassingen worden opgesplitst in fijnkorrelige, losjes gekoppelde componenten die via API-aanroepen met elkaar communiceren.
• Containers: Tijdens CI/CD worden alle softwaretoepassingen en al hun afhankelijkheden gesegmenteerd naar specifieke beperkingen om de overdraagbaarheid van de oplossing tussen de omgevingen te verbeteren.
• Orkestratie: Some of the examples include Kubernetes, which helps manage a cluster for running applications and deploying and scaling containerized applications.
• DevOps: Pinpoints the core concept of cooperation between development, operation, and security teams to increase the efficiency of software release.
• Continuous Integration/Continuous Delivery (CI/CD): Focuses on automating and streamlining development processes to allow for more frequent, iterative releases with rapid feedback, reducing the reliance on manual tasks.

Cloud-native structures and DevOps practices commonly correspond with each other’s philosophies and objectives. The availability of cloud-native modularity for CI/CD optimization through Automatisering leads to recurring integration, testing, and deployments.

 This combination can influence feedback loop duration, software quality, and the speed at which oplossingen de markt bereiken.
