Best Application Delivery Controllers (ADC) for Elastic Observability

Safeguard your applications against prevalent web threats such as SQL injection and cross-site scripting. Utilize custom rules and groups to monitor your web applications, catering to your specific needs while minimizing false positives. Implement application-level load balancing and routing to create a scalable and highly available web front end on Azure. The autoscaling feature enhances flexibility by automatically adjusting Application Gateway instances according to the traffic load of your web application. Application Gateway seamlessly integrates with a variety of Azure services, ensuring a cohesive experience. Azure Traffic Manager enables redirection across multiple regions, provides automatic failover, and allows for maintenance without downtime. In your back-end pools, you can deploy Azure Virtual Machines, virtual machine scale sets, or take advantage of the Web Apps feature offered by Azure App Service. Centralized monitoring and alerting are provided by Azure Monitor and Azure Security Center, complemented by an application health dashboard for visibility. Additionally, Key Vault facilitates the centralized management and automatic renewal of SSL certificates, enhancing security. This comprehensive approach helps maintain the integrity and performance of your web applications effectively.

NGINX Open Source is the web server that supports over 400 million websites globally. Built upon this foundation, NGINX Plus serves as a comprehensive software load balancer, web server, and content caching solution. By opting for NGINX Plus instead of traditional hardware load balancers, organizations can unlock innovative possibilities without being limited by their infrastructure, achieving cost savings of over 80% while maintaining high performance and functionality. It can be deployed in a variety of environments, including public and private clouds, bare metal, virtual machines, and container setups. Additionally, the integrated NGINX Plus API simplifies the execution of routine tasks, enhancing operational efficiency. For today's NetOps and DevOps teams, there is a pressing need for a self-service, API-driven platform that seamlessly integrates with CI/CD workflows, facilitating faster app deployments regardless of whether the application utilizes a hybrid or microservices architecture, which ultimately streamlines the management of the application lifecycle. In a rapidly evolving technological landscape, NGINX Plus stands out as a vital tool for maximizing agility and optimizing resource utilization.

Elastic Load Balancing efficiently directs incoming application traffic to various destinations, including Amazon EC2 instances, containers, IP addresses, Lambda functions, and virtual appliances. It allows you to manage the fluctuating load of your application traffic across a single zone or multiple Availability Zones. With four distinct types of load balancers, Elastic Load Balancing ensures that your applications maintain high availability, automatic scalability, and robust security, making them resilient to faults. As an integral part of the AWS ecosystem, it is designed with an understanding of fault limits, such as Availability Zones, which ensures your applications remain operational within a single region without the need for Global Server Load Balancing (GSLB). Additionally, ELB is a fully managed service, enabling you to concentrate on application delivery rather than the complexities of deploying numerous load balancers. Furthermore, capacity is dynamically adjusted based on the demand for the underlying application servers, optimizing resource utilization effectively. This intelligent scaling capability allows businesses to better respond to varying traffic levels and enhances overall application performance.
