Security Modeling for Reliability and Resilience

Security Modeling for Reliability and Resilience

What are Security Models Information systems use security models, which are a list of operations for evaluating and authenticating security policies.  This helps to map policy goals to information systems through the specification of explicit data structures and techniques needed for implementing the said security policy. A security model can be represented in mathematical form as well as analytical ideas.… Continue readingSecurity Modeling for Reliability and Resilience

Event Driven Architecture

How to Leverage Event-Driven Architecture for Microservices with AWS

A decoupled Service-Oriented Architecture is the blueprint for a microservices architecture. So microservices applications are designed and developed as a collection of loosely coupled services with private databases each per service. But then you may use different SQL or NoSQL databases for each service as per the kind of data you store and process within each service. That means you… Continue readingHow to Leverage Event-Driven Architecture for Microservices with AWS

Save Cloud Spend

How does Kubernetes Save Cloud Spend?

Containerization of software applications is a major disruption of the decade in the IT industry. Software containers could automate deployment and management of multiple distributed applications across multiple physical and/ or virtual machines including the cloud space. In the meantime, the birth of Kubernetes could shift the developers’ focus and effort from managing machines to managing applications. Container Orchestration with… Continue readingHow does Kubernetes Save Cloud Spend?

Microservice Architecture Best Practices and Patterns

Database per Microservice After organizations switch from monolithic systems to smaller microservices, they still choose to go along with a big central database. Although this method provides advantages in the short term, it will prove to be problematic in the long term. That’s because microservices have a close relation with the database layer. Thus, the purpose of creating microservices will… Continue readingMicroservice Architecture Best Practices and Patterns
