Cloud adoption has transformed how developers build and scale applications, but it also brings new challenges in controlling costs. As cloud bills grow alongside usage, designing cost-efficient cloud architectures becomes essential for developers, DevOps specialists, architects and team leaders.

This post explores key strategies for optimizing cloud expenditure and align it with actual needs without incurring cloud wastage spend.

Kubernetes, also known as K8s has become the de facto platform for orchestrating modern microservices architectures, promising resilience, scalability and faster deployment pipelines for Java applications. But for many developers, that promise often hides a thorny reality: Kubernetes is powerful—but also painfully complex.

Cloud computing has transformed how enterprises deploy and manage applications. A cloud server provides an on-demand, scalable infrastructure that enables businesses to launch services without heavy upfront investments in hardware. Whether used for hosting, data management, or large-scale application deployment, cloud servers are now integral to modern IT ecosystems. This is especially true for Java EE and Jakarta EE applications, where cloud-native environments based on cloud application servers deliver agility, resilience, and cost-efficiency.  

In this blog, we look at what cloud application servers are, how they work, key benefits, use cases and real-world applications. 

Multi-cloud developments can offer real operational advantages. However, careful and strategic planning is key to maximize the gains. In fact, without clear operating models or setups, teams can experience costly missteps and cloud spent wastage. 

At Payara Services, we work closely with organizations deploying mission-critical enterprise Java applications across hybrid and multi-cloud environments. As a result, our engineering team has been actively engaged in helping companies succeed in their multi-cloud strategies, and we know first-hand what works best as well as common pitfalls. In this blog post, we look at what multi-cloud is and share key insights and tips to optimize your multi-cloud projects.

As more and more organizations embrace the cloud, Platform as a Service (PaaS) solutions for application deployment and management are becoming more popular among development and DevOps teams. The promise of faster deployments, simpler maintenance, and more time for innovation is hard to ignore for teams of any size. But what are professionals really saying about PaaS and how can you make the most of it for your next project? 

We dug through candid insights from engineers, CTOs and founders and summarized our key findings in this blog post.

Almost any developer looking to leverage containers turns to Kubernetes (K8s) for orchestration. However, with its complexity comes security risks, particularly misconfigurations, which remain one of the most critical attack vectors in cloud-native environments. In effect, K8s misconfigurations can lead to data breaches, privilege escalations and service disruptions. 

This blog examines key technical security challenges associated with K8s and demonstrates how to mitigate these risks through platform engineering. 

Choosing the right application server is critical for the success of enterprise-grade applications. While Red Hat’s JBoss is a commonly implemented solution, organizations may want to explore alternatives to their current applications servers and runtimes. Sure, migrations can be intimidating, but if JBoss is no longer a perfect fit for a specific application, a move can help meet specific requirements, such as cutting licensing costs or adopting cloud-native approaches, as well as unlock new opportunities or capabilities.  

If you're here, chances are you’re considering your options. In this blog, we’ll discuss what JBoss offers, why businesses look for alternatives as well as what key contenders to look for when exploring alternatives. 

What is JBang?

JBang is a tool that lets you run Java code with zero build setup. It handles dependencies, compilation, and execution with a single command - making Java as easy to run as a script. With JBang, you can:
