Modern Analytics and End-to-End Visibility

July 3, 2019 — by Prakash Sinha0

Many Cloud Service Providers (CSP) and large enterprises struggle to deliver a commitment level for an application service. For a tenant, without a proper Service Level Agreement (SLA), it is impossible to manage an application for his or her own users.

Delivering SLA without first gaining end-to-end visibility for an application, user and network is asking for trouble. This has long been an area of contention and finger pointing between network and application teams. Solutions for monitoring application performance and SLA are expensive and the task is complex, requiring inserting hardware probes and/or integrating software agents into every application server.

The Case for Application Analytics

Application analytics provides deep insights into application, user and network behavior and the root cause of an SLA breach by capturing, analyzing and visualizing application metrics.

When deploying applications, particular attention is required to see when things are slowing, so proactive monitoring becomes critical. Not only is proactive monitoring and troubleshooting through actionable insights helpful in configuring the appropriate technical capability to address the issue at hand, this visibility into application performance is important in terms of cost saving. For example, to de-provision unused resources when not needed or to mitigate an attack in progress.

An SLA breach may be due to device outage or configuration issues, problems of access from a particular geography, a specific device type, a particular data center, or something in between. Other reasons may be SSL handshake issues or security attacks that impacting application performance due to a lack of resources. It is important to know these issues before they become a business disruption.

In a multi-tenant environment, if the environments are not segregated, tenants may start competing for shared resources during peak utilization. In an environment where tenants share resources, a potential spike in resource consumption or a wrong configuration change of a single tenant may affect all other tenants – severely impacting an application’s SLA and availability.

End-to-End Visibility

Application Delivery Controllers are at the intersection of the network and applications. ADCs act as sensors to changing user demands of the applications – for example, detecting increased user latency or a lack of available application resources, or reaching a throughput limit, or outage of a specific service or a security attack in progress.

In order to detect any application performance issues in real-time before your customers experience them, it is essential to have an end-to-end monitoring capability that provides actionable insights and alerts through visualization. The ADC can act upon this telemetry to trigger automation and orchestration systems to program the applications or the network elements as needed.

Keeping Pace in the Race for Flexibility

February 27, 2019 — by Radware2

Flexibility and elasticity. Both rank high on the corporate agenda in the age of digital transformation and IT is no exception. From the perspective of IT, virtualization and cloud computing have become the de facto standard for deployment models. They provide the infrastructure elasticity to make business more agile and higher performing and are the reason why the majority of organizations today are operating within a hybrid infrastructure, one that combines on-premise with cloud-based and/or virtualized assets.

But to deliver the elasticity promised by these hybrid infrastructures requires data center solutions that deliver flexibility. As a cornerstone for optimizing applications, application delivery controllers (ADCs) have to keep pace in the race for flexibility. The key is to ensure that your organization’s ADC fulfills key criteria to improve infrastructure planning, flexibility and operational expenses.

One License to Rule Them All

Organizations should enjoy complete agility in every aspect of the ADC service deployment. Not just in terms of capabilities, but in terms of licensing . Partner with an ADC vendor that provides an elastic, global licensing model.

Organizations often struggle with planning ADC deployments when those deployments span hybrid infrastructures and can be strapped with excess expenses by vendors when pre-deployment calculations result in over-provisioning. A global licensing model allows organizations to pay only for capacity used, be able to allocate resources as needed and add virtual ADCs at a moment’s notice to match specific business initiatives, environments and network demands.

The result? Dramatically simplified ADC deployment planning and a streamlined transition to the cloud.

An ADC When and Where You Need It

This licensing mantra extends to deployment options and customizations as well. Leading vendors provide the ability to deploy ADCs across on-premise and cloud-based infrastructures, allowing customers to transfer ADC capacity from physical to cloud-based data centers. Ensure you can deploy an ADC wherever, whenever they are required, at the click of a button, at no extra cost and with no purchasing complexity.

Add-on services and capabilities that go hand-in-hand with ADCs are no exception either. Web application firewalls (WAF), web performance optimization (WPO), application performance monitoring…companies should enjoy the freedom to consume only required ADC services rather than overspending on bells and whistles that will sit idle collecting dust.

Stay Ahead of the Curve

New standards for communications and cryptographic protocols can leave data center teams running amok attempting to keep IT infrastructure updated. They can also severely inhibit application delivery.

Take SSL/TLS protocols. Both are evolving standards that ensure faster encrypted communications between client and server, improved security and application resource allocation without over-provisioning. It allows IT to optimize the performance of applications and optimize costs during large scale deployments.

Combining the flexibility of an ADC that supports the latest standards with an elastic licensing model is a winning combination, as it provides the most cost-effective alternative for consuming ADC services for any application.

Contain the Madness

The goal of any ADC is to ensure each application is performing at its best while optimizing costs and resource consumption. This is accomplished by ensuring that resource utilization is always tuned to actual business needs.

Leading ADC vendors allow ADC micro-services to be added to individual ADC instances without increasing the bill. By supporting container orchestration engines such as Kubernetes, it allows the organization to adopt their ADC to the application capacity. This also simplifies the addition of services such as SSL or WAF to individual instances or micro-services.

Finding an ADC vendor that addresses all these considerations requires expanding the search from focusing on mainstream vendors. To drive flexibility via IT elasticity means considering all the key ADC capabilities and licensing nuances critical to managing and optimizing today’s diversified IT infrastructure. Remember these three
keys when evaluating ADC vendors:

  • An ADC licensing model should be an catalyst for cutting infrastructure expenditures, not increasing them.
  • An ADC licensing model should provide complete agility in ever aspect of your ADC deployment.
  • An ADC license should allow IT to simplify and automate IT operational processes.

Should Business Risk Mitigation Be A Factor When We Choose Our Suppliers And Manufacturers?

July 24, 2018 — by Daniel Lakier53

supplier-manufacturer-960x640.jpg

This is something that I have struggled with for most of my working life. As a technology professional, it is my job to pick the best products and solutions or to dig deeper to marry that technological decision with one that’s best for my organization. Is it incumbent on me to consider my suppliers’ financials, or their country or origin, or perhaps their business practices?

This thought was thrust sharply into focus during the past few months. First, we were reminded that a sound business still needs to have sound financials. The second warning is around the ramifications of a trade war.

Marrying the Business Need With Technology, Part 3: Re-aggregating the Tools

January 18, 2018 — by Daniel Lakier0

In part one of this blog series we discussed how there is oftentimes a lack of knowledge when it comes to infrastructure technology and knowhow in the relevant DevOps teams. This is not what was intended when “Agile” moved from being a pure development approach to a whole technology management methodology, but it is where we find ourselves. One of the consequences we face because of this is that the traditional user of many technologies, the developers/application owners, know what functionality they should have but not where to get it.

In today’s world, digital transformation has changed how people interact with businesses and conduct their work. They interface with applications on the network. These applications need to be responsive and provide a quality of experience that enables people to appreciate the business and the services they provide. When an application degrades in performance, it negatively affects the user’s experience. This negative experience translates to lost value to revenues, brand, and worker productivity.

If you are like most people and myself, you do not go into a bank and have a conversation with a teller when you make a deposit or withdrawal. You probably do not write paper checks and sign them. You have an app on your phone to access your bank account and use one of the thousands of automated teller machines (ATM), around the world to move money in and out of your accounts.
