Network Configuration Management is a Key Component in Business Today

NMSaaS Network Configuration Management

Network configuration management is the process of organizing and maintaining information about all the components of a computer network.

When a network needs repair, alteration, development or advancements, the administrator refers to the network configuration management database to determine the best course of action.

This database contains the locations and network addresses of all hardware devices, as well as information about the programs, versions and updates installed in network computers.

There are many advantages you have while implementing configuration management such as:

  • Minimizing configuration errors.
  • Minimizing downtime.
  • Optimizing network security.
  • Improving the processes of maintenance, repair, and expansion and upgrading.

Companies such as Cisco have been developing network configuration applications for years now and they feel it is a necessity and not an option in business today.

By using it, it allows you to roll out configuration changes to numerous network devices within minutes rather than hours, or even days. Push out a config change in real time or schedule it for after hours.

It makes you take advantage of the central repository for all network devices by automatically backing up your configurations. This automated approach allows you to sleep at night knowing that you can always have the most up to date configurations of your devices.

The web interface quickly gives you a user friendly snapshot of the status of your devices providing you the knowledge of what devices are backed up, not backed up, have start/run conflicts, etc.

One of the main leaders in the tech industry Infosim has come out with statement saying that

“Through 2015, 80% of outages impacting mission-critical services will be caused by people and process issues, and more than 40% of those outages will be caused by change, configuration, release integration and hand-off issues.”

This can all be easily avoided by using one of our configuration applications. To find out more get in contact with the team.

Network Strategies for 2015

As we say goodbye to 2014 and review our network equipment plans for the new year, looking at replacement options is not enough.

We have to consider the currents that network technology flows in and where they are taking us.

Ignoring buying decisions and looking at the bigger picture provides an opportunity to assess what emerging companies are doing to redefine and redirect our network thinking, from the higher levels of standardisation, convergence and virtualisation down to how startups are meeting these challenges.

Here is what you should be aware of in 2015.

Standardisation

2015 will see the shifts in IT investments move towards standardised hardware and software products. The software and hardware standardisation efforts inherent in software-defined networks (SDN) and network function virtualisation (NFV) initiatives in the wide area network (WAN) will affect corporate network

Virtualisation

Existing datacentre hardware is being optimised in virtualised environments, and applications are being farmed out to public cloud providers, significantly changing the hardware equation.

Convergence

Hyperconverged infrastructure products combine compute, networking and storage resources to create all-in-one solutions. Hyperconverged appliances offer the scale-out architecture that fits the needs of most shared virtualised environments. To facilitate this, unified software packages have been adopted to converge networking functions previously allocated to dedicated hardware boxes such as WAN optimisers, packet shapers, application development controllers, application and network performance managers, load balancers and next-generation firewalls. This means storage and security are becoming intrinsic to networking topologies and, as such, will become embedded in networking hardware and software.

New challenges in 2015

The specific board-level demands to most enterprise network managers in 2015 will include:

  • Handling 100% traffic growth with the same budget as in 2014.
  • Recognising that much of that traffic growth, namely video, will be latency sensitive.
  • Ensuring the growing bring your own device (BYOD) demand for connectivity is secure and delivers quality of service (QoS) to the customers.
  • Minimising capital expenditure and go with industry-standard, bare-metal hardware to support SDN/NFV.
  • Maximising operating expenses in software and hardware deals.

This translates into key concepts around aligning networks to support business processes, shifting more traffic to Ethernet, flexible cloud deployments and better integration of security and storage capabilities. Startups present interesting next-step products to dominant suppliers in all these categories.

Aligning Network Hardware To Business Processes

When the buyer focus shifts to commoditisation, this presents a serious challenge to profit margins for premium network hardware brands such as Cisco, HP and IBM. Conversely, it presents an opportunity for nimble startups in the network hardware business, as brand loyalty is eroded and the focus shifts to supporting horizontal business processes.

Startup hardware suppliers are adopting the same hyperconvergence logic as software suppliers by integrating complementary software functionality into their boxes to facilitate core business processes. The result is hardware with better integration levels, cheaper and simpler deployments and easier scale-out capacity than their software and brand-name competitors. Instead of outsourcing functions, these network hardware startups advocate on-premise enterprise networking strategies. The message certainly whets the appetite of investors.

They are not looking for startups selling Lego blocks for DIY constructions, but rather emerging suppliers with the integrated hardware and software to handle specific business needs with faster time to value than existing value propositions on the market. Market leader VMware, with its Evo: Rail concept, has aligned all parts of its vSphere and Virtual SAN (storage area network) ecosystem with seven hardware partners (Dell, EMC, Fujitsu, Inspur – China’s dominant cloud computing and service provider, NetOne – Japanese infrastructure optimiser, HP, and SuperMicro – the US application-optimised server, workstation, blade, storage and GPU systems provider).

Startup company Scale Computing, with its HC3 platforms, presents an interesting challenge to the Evo: Rail design, aimed at small and medium-sized enterprises (SMEs), and values simplicity and fast deployment. The three HC3 platforms scale from 40 to 400 virtual machines (VMs). Scale Computing uses a customised version of Red Hat’s KVM hypervisor and leverages a block-level storage architecture as opposed to Virtual SAN’s (VSAN) object-based approach. While KVM may not have as many features as vSphere, Scale Computing is banking on the simplicity of operation along with aggressive pricing compared to the competition, and uses a scale-out architecture that can handle four nodes as the infrastructure grows.

Large enterprises should look at the startup Simplivity and its OmniCube, a hyperconverged infrastructure that delivers the economies of scale of a cloud computing model while ensuring enterprise IT performance and resiliency for virtual workloads. OmniCube has a data architecture that addresses data efficiency and global management requirements in virtualised and cloud computing environments. Its single unified stack runs on standard and hyperconverged x86 building blocks, simplifying and lowering the cost of infrastructure. Deploying a network of two or more OmniCubes creates a global federation that facilitates efficient data movement, resource sharing and scalability.

Ethernet deployments

Ethernet adoption continues to expand and startups such as Arista provide important contributions with the 10-1000Gbps Ethernet switches that target cloud service providers with purpose-built hardware. Its EOS network operating system provides single-binary system images across all platforms, maximum system uptime, stateful fault repair, zero-touch provisioning, latency analysis and a fully accessible Linux shell. With native support for VMware virtualisation and hundreds of Linux applications integrated into hardware platforms, it is designed to meet the stringent power and cooling requirements of today’s most demanding datacentres.

Cloud in a box

In the SME market, SixSq’s Nuvlabox offers a turnkey private cloud in a box. The Mac Mini-sized box includes a complete infrastructure as a service (IaaS) framework, powered by StratusLab, and a platform as a service (PaaS) powered by Slipstream. The built-in Wi-Fi provides network connectivity. With the ability to run up to eight VMs, capacity constraints are solved by adding more boxes and managing them as a single unit. Nuvlabox comes with a library of standard apps and operating system images, including different flavours of Linux and Windows and allows secure remote monitoring and application deployment from a single dashboard. To bypass the capital expenditure objection, SixSq has shifted its business model towards business-to-business licensing, where service provider customers pay rental fees for the equipment and SixSq provides ongoing maintenance and call centre support.

Network Security

Increased use of IT adds value to corporate network transactions and attracts a lot of unwelcome attention. In 2015, we expect more hackers, script kiddies, professional thieves and state-sponsored advanced persistent threat (APT) attacks to target corporate networks. But there is still a lot of low-hanging fruit to gather, such as increased employee awareness of weak passwords and phishing exploits, faster remediation of security holes and better denial of service protection measures. There is also a need for better tools and procedures to protect the enterprise network and ensure these measures meet corporate governance, risk and compliance (GRC) requirements.

One supplier aiming to address these needs is Bromium, which combines a software client on any device with a central security server. Instead of using signatures, behaviours or heuristics to identify potential threats, its vSentry client creates hardware-isolated micro‑VMs for every network-related task, such as visiting a web page, downloading a document or opening an email attachment. All micro-VMs are separated from each other and from the trusted enterprise network. Thus, malware is contained in the hardware-isolated micro-VM. Bromium’s Live Attack Visualization and Analysis (Lava) server converts each micro-VM in the enterprise into a honeypot and automates the often prolonged post-attack malware analysis process. An entire attack is automatically and instantly forwarded to the Lava console, which provides an automatic in-depth analysis of the advanced malware.

Network Storage

Video and social network communications from mobile devices with always-on technology has mushroomed data flows. In the enterprise, big data analytics relies on huge volumes of unstructured data, itself often comprised of large file formats that require secure storage and fast retrieval capacity. Network data volumes are moving from exabyte to zettabyte levels of data and higher. Most pundits and some analyst firms predict traffic and storage volumes will continue to double every two years. Next-generation storage systems include hyperscale data storage, virtualisation to improve utilisation, cloud storage for disaster recovery and lower power consumption to save costs. To enhance storage security, storage systems may incorporate data dispersal and keyless encryption to keep data secure against breaches.

The startup company Solidfire has developed a storage system built on the native ability to achieve significant scale, guarantee storage performance, and enable complete system automation. Combined with enterprise applications and deeply integrated with key management frameworks, Solidfire delivers validated products that make a next-generation datacentre deployment more cohesive, automated, and dynamically scalable.

At the high end, Insieme Networks is the driving force behind Cisco’s Application Centric Infrastructure (ACI) at the core of Cisco’s long-awaited SDN strategy. The ACI architecture leverages a mix of merchant and custom Asics, along with Cisco’s new line of Nexus 9000 switches and its Application Policy Infrastructure Controller (APIC).

Establishing business models

Startup companies in the network hardware business are not only introducing new technology perspectives, they are also exploring new business models and establishing customer relationships. Building on standardised platforms allows users to do more process management and security tasks themselves. With higher levels of personalisation and control, users can more easily explore alternative business processes and combine functions across different platforms, which translates into faster time to value. 2015 promises to be an exciting year for enterprise IT departments looking to revamp their corporate network infrastructures – they may actually meet their boards’ network targets.

A Unified View of Network Monitoring

NMSaaS Unified Network Monitoring

In the past few years, the enterprise computing technology has changed dramatically. Virtualization, SaaS, and cloud computing are creating fundamental changes, and leading to an time in which enterprises distribute critical IT applications across multiple service providers and infrastructure. These changes are rendering legacy monitoring tools, which have their roots in the computing environments of a decade or more ago, virtually useless. This paper explores today’s computing trends and their monitoring implications. In addition, it reveals how a new monitoring paradigm, the NMSaaS architecture, uniquely addresses the monitoring realities of today’s and tomorrow’s enterprises—whether they rely on internal platforms, external service providers, or a combination of both.

The 5 Main Questions You Have to Ask in Network Management

Cloud Computing

Although many people may perceive Network Management as an extremely complicated and diverse area of specialty, there really are only 5 questions that every Network Manager needs to think about. The main components behind every problem in Network Management, are as follows:

What do I have?

If you don’t know what you have how can you manage or monitor it. Most of the time in Network Management you’re trying to track down potential issues and how you’re going to resolve these issues. This is a very hard task especially if you’re dealing with a large scale network. If one thing goes down within the network it starts a trickle effect and then more aspects of the network will in return start to go down.

If you don’t know what you have how are you meant to know if you need an upgrade. Numerous enterprises are paying for upgrades that aren’t needed and getting charged for unnecessary maintenance. A simple tool like automated discovery management can help resolve this. It identifies what you have, displays topology maps and automatically compiles reports.

Is anything broken?

At times, technology seems like it is advancing faster than we can keep up with it. As the industry evolves, your business must adapt to take these changes, especially if you want to stay as efficient as possible. Finding out if there are any issues with your infrastructure sooner rather than later is an obvious factor, but some people find this harder than others with the size of their IT infrastructure.

Having the right Network Management solution enables you to find the flaws early on so they don’t snow ball into a catastrophe. Continuous monitoring of all systems ( devices, services, UPS’s) are all key components to eliminate these issues, an application such as Root Cause Analysis or Weathermapping can help you manage these complications.

Why is it slow?

The number one complaint is why is it slow? Everyone always presumes that it’s the networks fault that the application is slow, in reality there is a number of issues. These concerns include over capacity of links, poorly written applications, firewall problems or even QoS issues. Sometimes it’s tricky to find the actual cause of the application being slow as most of the time there is no evident issue to be found.

What can be done? TEST, TEST, TEST, and then correlate these to come up with a realistic resolution. You can use NetFlow to get a real deep dive into what’s going on.

Cloud Computing

Is it secure?

Is my network secure is a hot topic these times with breaches occurring in some of the top firm’s applications. Company’s such as JP Morgan, EBay and Snapchat have all had security threats in 2014 with a lot of their customer’s information being jeopardized. Many wonder if these networks are safe and the answer is that that they are.

There is always going to be vulnerabilities no matter what, in the first of half 2014 there were over 400 security breaches within companies withholding personal information. As long as you have a trusted network manager you should be ok, a lot of these hacks are just wake up calls for companies to improve their security network.

Our approach to security is to create, push and perform security policies. Every network application should have a good protection policy configuration. Here at NMSaaS we can create those policy checking systems which have the possibilities to take down any possible vulnerabilities and eliminate them.

Can I recover if something fails?

In reality nothing lasts forever, the average life span for a hardware device is 4 years. The main concern is are you able to recover your data if a problem arises, and the answer is yes.

What to do

  • Back up all of you device configuration files (off site)
  • Maintain a consistent schedule of backups.
  • Have a quick and simple restoration process if something does fail.
  • There are always going to be problems no matter what, but what you have to remember is that there is always a solution to every problem!

Aligning IT with Business via Performance Management

Much of the discussion around the Observer Platform 17 release has focused on how the designs of the new user interface (UI) and other enhancements will assist network and operations teams to more easily manage service and application performance.

This performance data and analysis isn’t just of value to IT but to the overall business. The challenge for performance management solutions has been providing this intelligence in a way that can be easily accessed and understood by other IT and business teams. The Observer Platform 17 both expands useful analysis available to business groups and makes it easier to use the data with systems familiar to these groups.

Enhancement: Expanding Web Service Analytics

  • Benefit: Strengthens visibility into how users consume company web resources, specifically as it relates to a web-based app’s device parameters like OS, mobile and desktop platform details, and browser type.
  • Business Value: Knowing not just “what” but “how” customers are accessing data is pivotal to optimizing web content and quantifying the effectiveness of customer-facing web interactions.
  • In Practice Example: For the marketing team launching web initiatives, these metrics provide details on how visitors are accessing the website, and enhance their understanding of the user experience by providing response-time and error metrics. Additionally, when network-based problems occur that impact marketing web programs, they can be resolved by the network team which has access to the packets.

JDSU Network Instruments Observer 17 Platform

Enhancement: Third-Party System Integration via RESTful APIs

  • Benefit: Simplifies sharing of performance data with other groups. RESTful APIs are a programming interface that utilizes HTTP requests like GET, PUT, POST and DELETE. Using this universal access method enables any solution to connect to the Observer Platform to access data or even manage the solution remotely.
  • Business Value: Other teams in an organization can interact and view performance data and analysis from the Observer Platform from the tools and workflows that they use on a daily basis. This allows them to proactively track performance of critical business systems, and view these metrics alongside business metrics.
  • In Practice Example: A support staff for a retail chain could integrate the Observer Platform into their helpdesk system via Apex’s RESTful API to monitor points of sale (PoS) on their network. The Observer Platform could instantly alert the service desk of an anomaly or system condition that could soon negatively impact users. The early alerts, performance analysis, and access to packets allow the staff to take proactive steps to remediate the issue before it impacts the PoS and customers.

With IT playing a key role in helping businesses to develop competitive advantages and nimbly respond to changing markets, it’s critical that network teams can facilitate the sharing of performance intelligence. This also allows IT and business teams to evaluate the success of business operations and initiatives. The new features of the Observer Platform 17 mark a significant step forward in enabling the network team and IT to more closely align with business processes and goals.
