Evaluating NFV and SDN: Key Considerations Making informed network investment decisions about emerging technologies such as network function virtualization (NFV) and software-defined networking (SDN) can help evolve the network to keep pace with the innovations of the devices and people it's connecting. As you work with business leaders to make decisions about upgrading your infrastructure with these networking developments, it's important to understand the similarities, differences, and benefits of dual NFV and SDN implementation. With their ability to offer a new way to design, deploy, and manage the network and its services, NFV and SDN should be incorporated into modern enterprise networks and carrier infrastructures. However, lack of knowledge about these technologies can result in poor networking investments and missed opportunities to experience the benefits... (more)

[slides] Embracing Software Defined | @CloudExpo @BHIvanov @StorPool #SDN

Embracing Software Defined: From Theory to Practice As Marc Andreessen says software is eating the world. Everything is rapidly moving toward being software-defined - from our phones and cars through our washing machines to the datacenter. However, there are larger challenges when implementing software defined on a larger scale - when building software defined infrastructure. In his session at 16th Cloud Expo, Boyan Ivanov, CEO of StorPool, will provide some practical insights on what, how and why when implementing "software-defined" in the datacenter.

Serverless Is Here | @CloudExpo #FaaS #CloudNative #Serverless #DevOps

What Is Function-as-a-Service? Serverless Architectures Are Here By Matt Watson It has never been a better time to be a developer. Thanks to cloud computing, deploying our applications is much easier than it used to be. How we deploy our apps continues to evolve thanks to cloud hosting, Platform-as-a-Service (PaaS), and now Function-as-a-Service. What Is Function-as-a-Service (FaaS)? FaaS is the concept of serverless computing via serverless architectures. Software developers can leverage this to deploy an individual "function", action, or piece of business logic. They are expected to start within milliseconds and process individual requests and then the process ends. Principles of FaaS: Complete abstraction of servers away from the developer Billing based on consumption and executions, not server instance sizes Services that are event-driven and instantaneously scala...

Java Virtual Machine | @CloudExpo @Stackify #DX #JVM #Java #Virtualization

A Deep Dive into the Core Metrics of the Java Virtual Machine By Eugen Paraschiv Overview of JVM Metrics In this article, we'll cover how you can monitor an application that runs on the Java Virtual Machine by going over some of the critical metrics you need to track. And, as a monitoring tool, we'll use Stackify Retrace, a full APM solution. The application we'll monitor to exemplify these metrics is a real-world Java web application built using the Spring framework. Users can register, login, connect their Reddit account and schedule their posts to Reddit. How JVM Memory Works There are two important types of JVM memory to watch: heap and non-heap memory, each of these with its own purpose. The heap memory is where the JVM stores runtime data represented by allocated instances. This is where memory for new objects comes from, and is released when the Garbage Colle... (more)

Don’t Get Lost in the Cloud | @CloudExpo @RackWare #Compliance #AI #DX #HybridCloud

For most organizations, the move to hybrid cloud is now a question of when, not if. Fully 82% of enterprises plan to have a hybrid cloud strategy this year, according to Infoholic Research. The worldwide hybrid cloud computing market is expected to grow about 34% annually over the next five years, reaching $241.13 billion by 2022. Companies are embracing hybrid cloud because of the many advantages it offers compared to relying on a single provider for all of their cloud needs. Hybrid offers balance and flexibility. It helps companies achieve a wide array of business goals, including availability, reliability, security and cost-efficiency. Still, there are a number of challenges associated with hybrid cloud. Here are four management issues that companies need to address to enjoy a successful hybrid cloud implementation. Managing complexity. More clouds can sometimes... (more)

Java Heap Space vs. Stack Memory | @CloudExpo #JVM #JRE #Java #AI #DX

Java Heap Space vs. Stack Memory: How Java Applications Allocate Memory By Angela Stringfellow Java applications need a certain amount of RAM on a computer to run. Each time an object or variable is declared, it needs more RAM. Simply designating enough memory to hold every value declared and run each method would lead to a bloated application. To keep application memory requirements lean, it is partitioned in ways that require less memory and allows the application to run more quickly. The Java Virtual Machine (JVM) divides memory between Java Heap Space and Java Stack Memory in a way that only uses memory that's needed. What Is Java Heap Space It is created by the Java Virtual Machine when it starts. The memory is used as long as the application is running. Java runtime uses it to allocate memory to objects and Java Runtime Environment (JRE) classes. When an object i... (more)

Support Costs of VPN Software for File Remote Access | @CloudExpo #SDN #Cloud #Virtualization

Accessing files using traditional VPN software comes at a great cost. In this article we quantify true costs of supporting VPNs for remote access. Businesses of all types utilize VPN software solutions to provide remote access to their employees.  How do we quantify the true Total Cost of Ownership (TCO) of supporting VPN software?  Why is TCO Important? Gartner, Inc. (www.gartner.com) defines TCO as the total cost of using and maintaining an IT investment over time.  TCO calculations include a combination of direct costs (hardware, software acquisition, management and support) and indirect costs (end-user training and downtime). TCO is often overlooked and unbudgeted, presenting an incomplete projection of overall IT costs. Most organizations look at their direct costs and setup labor only at the time of purchase.  However, research shows that a system's software & ... (more)

A Tool Is About What You Need It For | @DevOpsSummit #DevOps #CloudNative #Serverless

We seem to run this cycle with every new technology that comes along. A good idea with practical applications is born, then both marketers and over-excited users start to declare it is the solution for all or our problems. Compliments of Gartner, we know it generally as “The Hype Cycle”, but each iteration is a little different. 2018’s flavor will be serverless computing, and by 2018, I mean starting now, but going most of next year, you’ll be sick of it. We are already seeing people write such sweeping statements as “The purpose of serverless is no-ops”. And that type of declaratory language is going to get worse. One time, very slowly: Right now, in the case of public cloud vendors, the purpose of serverless is to lock you in. It is that simple. They want to add value that will keep your dollars flowing into their coffers. And they do not at all mind if the proce... (more)
