Modernising the data center is the way towards digital and DevOps

Business and IT leaders agree that data center and cloud transformation will yield big benefits, ranging from greater business agility and responsiveness to change, greater cost efficiencies and faster time to innovation for new applications.

But that doesn&#rsquo;t necessarily mean scrapping everything that already exists within the business and starting from scratch. Instead, businesses can bring their IT environment up-to-date by modernising the infrastructure, automating IT and running modern apps.

Data center modernisation is at the heart of this movement to change.

For some businesses it could mean a move to DevOps, for others it could be a shift to transforming into a digital business. Many are striving for both. Either way, data center modernisation can lead to a significant boost in speed and agility – two key attributes at the heart of DevOps and digital transformation.

Take Amdocs, a market leader in customer experience software and services. The company had a challenge to provision an environment for developers and testers to work quickly without depending on IT.

&#rsquo;Previously, it took us between three hours to three days to provision an environment, which is market standard. It wasn&#rsquo;t enough for us,&#rdquo; said Golan Remi, Head of Global Business Technologies at Amdocs IT.

&#rsquo;We needed to transform our code from development through testing for the customer in record time, so we conducted a POC with multiple private cloud vendors. The VMware solutions proved to be the closest to our requirements and the easiest to install and operate,&#rdquo; he explained.

The organisation deployed a large-scale private cloud based on VMware&#rsquo;s software-defined data center (SDDC) architecture. It allowed Amdocs to provision thousands of vApps on a daily basis as part of Amdocs&#rsquo; automated DevOps processes.

Previously it took the organisation between three days to a few weeks to create a full environment for its developers – but this has all changed.

&#rsquo;Now, a developer can come to work, press a button, go and make a coffee and when they come back the environment is ready for them,&#rdquo; Remi said.

The company is able to globally provision an environment to all of its developers and testers with zero dependency on IT, while also significantly shortening its ramp up time and being more flexible to its customers&#rsquo; needs.

Another example of a company that has been implementing a DevOps philosophy is Telefonica, the huge digital telco with more than 300 million users in 21 countries across the world.

Its Senior DevOps Manager, Gustavo Martin Bouso, said that the company took the decision to refresh its hardware and storage using the hyper-converged system.

&#rsquo;The benefits including a reduction in cost, a reduction in complexity and having a scalable system. VMware is helping us with digital transformation,&#rdquo; he said.

It&#rsquo;s clear with these examples that with SDDC technologies, customers can modernise data centers for infrastructure flexibility, security, and scalability.

To go a step further, organisations can leverage VMware Cross-Cloud Architecture, easily extending this to public clouds, giving their developers an integrated hybrid cloud environment for deploying modern apps.

This is all part of their journey towards a DevOps culture and a digital future.

A Cross-Cloud approach is driving business innovation and agility

Organisations are constantly looking for greater business agility and a faster time to innovation for new applications – all while managing cost efficiency.

To do this, even the most successful businesses have to rely on new ways of integrating their technologies with other reliable and resilient partners that can take their capabilities up to a new level.

The VMware Cross-Cloud Architecture™ lets IT organisations easily leverage VMware hybrid clouds and manage multiple clouds.

Take two of our very own customers - CINIA Group, a successful IT services company that focuses on network, cloud and software, and Proact, Europe&#rsquo;s leading independent integrator for data center and cloud solutions. Both companies are incredibly successful at what they do – but instead of standing still, they have looked to provide new services and increase their existing capabilities.

CINIA Group, wanted to build a new Disaster Recovery-as-a-Service (DRaaS) for customers requiring critical infrastructure and availability on its Lioncloud.

It is based on VMware vCloud Availability for vCloud Director, with the support of partner Fluentscale.

Kristian Nieminen, Director of Cloud Services at CINIA Group said that the company built this new DRaaS on VMware technology because &#rsquo;it was the best of both worlds.&#rdquo;

&#rsquo;It&#rsquo;s a platform for modern cloud native workloads, and also performs as a robust and scalable platform for legacy systems,&#rdquo; he explained, adding that vCloud Availability for vCloud Director was selected as one of the core elements due to its easy integration to the existing Lioncloud infrastructure.

This is exactly what VMware Cross Cloud Architecture provides – an integrated architecture that supports customers&#rsquo; cloud strategies with freedom and control.

Nieminen added that this is backed with one of the best price-to-performance ratios – meaning that it is cost efficient too.

&#rsquo;vCloud Director proved to be versatile and easy-to-use technology. By using it, we have managed to build a cost-effective, powerful and very secure platform which is always available,&#rdquo; he said.

Like CINIA Group, Proact has been a VMware customer for a number of years. It has based all of its 22 datacentres on the VMware cloud management platform, giving customers who are at different stages of their journey to the cloud a number of options.

&#rsquo;Customers are all at different stages, both investment and technology wise, but with a hybrid cloud and VMware software-defined datacentre solution, they can select what kind of services they want to move to the cloud now, and leave the rest behind and slowly develop these into a full-cloud solution if they want to,&#rdquo; Proact&#rsquo;s Managing Director, Carsen Egeberg, explained.

He said that the biggest benefit of the Proact Cloud on VMware products is the time-to-market.

&#rsquo;This isn&#rsquo;t just time-to-market from an IT perspective but from a business perspective. [It helps with] entering new markets, cutting down costs – all the development any company in the world needs to stay above the water,&#rdquo; he said.

Proact&#rsquo;s hybrid cloud enables customers to stop thinking in physical layers and start thinking about services required for the company. It also gives them the opportunity to move services around freely between a local private cloud, a Proact hybrid cloud in one of its data centres, all the way out to the public cloud.

Our work with CINIA Group and Proact shows how we can help enterprises to confidently integrate public clouds to scale and extend their businesses, delivering agility, capacity, and resilience, and also accelerating innovation.

L’anno dell’infrastruttura iperconvergente

Motivi per cui i clienti ricorrono in massa all&#rsquo;infrastruttura iperconvergente:

L&#rsquo;avvento dell&#rsquo;infrastruttura iperconvergente (HCI) ha trasformato drasticamente i modelli di distribuzione rispetto alle operation IT in sili dell&#rsquo;ultimo decennio, rivoluzionando il modo in cui leaziende gestiscono storage, server e rete. Il trend di convergenza non mostra alcun segnale dirallentamento: secondo IDC, nel primo trimestre del 2017 l&#rsquo;aumento delle vendite di sistemi iperconvergenti si è attestato al 64,7% su base annua.

Possiamo quindi definire il 2017 come l&#rsquo;anno dell&#rsquo;HCI? Ecco cosa pensano i nostri esperti VMware:

L&#rsquo;aspetto più interessante è che non esiste un unico motivo specifico per cui le aziende si stanno indirizzando verso l&#rsquo;HCI. Si tratta di una soluzione che risolve numerose problematiche e che spesso garantisce vantaggi inaspettati per i clienti.

L&#rsquo;ufficio delle imposte della Catalogna, ad esempio, doveva affrontare molte sfide contemporaneamente. Javier Fernandez, Head of ITC, doveva gestire lamigrazione dei servizi aziendali verso un data center aziendale e l&#rsquo;upgrade dell&#rsquo;infrastruttura, che sipresentava in gran parte obsoleta. L&#rsquo;azienda doveva inoltre migliorare i propri livelli di sicurezza acausa della sensibilità dei dati che lo stesso ufficio delle imposte si ritrovava a gestire.

&#rsquo;I costi legati agli investimenti e alla manutenzione sono diminuiti drasticamente grazie alla riduzione rilevante delle infrastrutture e dei sistemi di comunicazione fisici&#rdquo;, ha dichiarato.

Lee Dilworth, EMEA Practice Lead, Storage & Availability, vede nel desiderio dei clienti di svolgere leattività in modo differente uno dei motivi del crescente uso dell&#rsquo;infrastruttura iperconvergente. L&#rsquo;infrastruttura HCI permette ai clienti di adottare un modello Pay As You Go per la creazione dei data center, iniziando con i componenti necessari al momento ma con la possibilità di scalare inbasealle esigenze future. Questa flessibilità rappresenta la differenza più eclatante rispetto aisistemilegacy, dove tutto è basato sull&#rsquo;overprovisioning e su ingenti investimenti iniziali di capitale.

La semplicità nella gestione e nella distribuzione, unita alla maggiore visibilità e alla disponibilità di un punto di gestione centralizzato, rende le infrastrutture iperconvergenti particolarmente appetibili per le aziende che hanno bisogno di funzionalità di data center remoti.

Un buon esempio è rappresentato dall&#rsquo;ONO Academic College, il più grande college in Israele. Allaricerca di un nuovo array di storage, ha deciso di adottare un&#rsquo;infrastruttura iperconvergente per ottenere maggiore flessibilità. Optando per una soluzione basata su dischi a stato solido, il college èstato in grado di conseguire prestazioni venti volte superiori, secondo il responsabile IT Oren Laufer, utilizzando vSAN per fornire un servizio di eccellenza anche ai propri siti remoti.

&#rsquo;Nella ricerca di un nuovo array di storage ci siamo imbattuti nel concetto di iperconvergenza, perfetto per le nostre esigenze di flessibilità&#rdquo;, ha affermato.

In questo modo, i tempi di backup si sono ridotti in modo significativo, ma non solo: ora è sufficiente una sola persona per gestire l&#rsquo;infrastruttura di storage virtuale, e il personale IT può dedicarsi allo sviluppo di nuove applicazioni anziché alle attività di routine.

In questa così come in molte altre aziende, VMware contribuisce a rendere più semplice la transizione a un&#rsquo;infrastruttura iperconvergente in grado di garantire un ROI in tempi rapidi. Oltreadavere un impatto sull&#rsquo;IT e sulla tecnologia, l&#rsquo;infrastruttura iperconvergente permette alpersonale IT di concentrarsi su problemi aziendali più rilevanti, quali il supporto a DevOps, losviluppodi iniziative di digital transformation e il conseguimento degli obiettivi strategici.

L’année de l’infrastructure hyperconvergée

Pourquoi les clients apprécient-ils tant l&#rsquo;infrastructure HCI?

Les modèles de déploiement ont profondément évolué, les infrastructures convergée et hyperconvergée (HCI) venant remplacer les opérations informatiques cloisonnées de la dernière décennie. Dans les entreprises, l&#rsquo;heure est au changement, avec l&#rsquo;adoption d&#rsquo;une nouvelle manière de gérer le stockage, les serveurs et le réseau. Et cette tendance vers la convergence ne devrait pas se ralentir: selon les statistiques relevées par IDC au premier trimestre2017, les ventes de systèmes hyperconvergés ont en effet augmenté de 64,7% en l&#rsquo;espace d&#rsquo;une année.

Pour savoir si nous pouvons légitimement déclarer que l&#rsquo;année2017 sera celle de l&#rsquo;infrastructure HCI, écoutons ce que les experts VMware en pensent:

Ce qu&#rsquo;il est intéressant de noter ici, c&#rsquo;est qu&#rsquo;il n&#rsquo;y a aucune raison particulière pour que les entreprises manifestent un tel engouement pour la HCI. En fait, ce type d&#rsquo;infrastructure apporte une solution à de nombreux problèmes et offre souvent des avantages dont les clients n&#rsquo;avaient même pas conscience.

Prenons l&#rsquo;exemple du département des services fiscaux de Catalogne, qui devait trouver des solutions aux difficultés rencontrées sur plusieurs plans. Javier Fernandez, son responsable TIC, devait notamment s&#rsquo;occuper de migrer les services de l&#rsquo;organisme vers un DataCenter leur appartenant et de mettre àniveau l&#rsquo;infrastructure, globalement obsolète. Le département devait également relever les niveaux de sécurité pour protéger convenablement les données sensibles qu&#rsquo;il traite.

«Dans la mesure où nous sommes parvenus à réduire largement l&#rsquo;infrastructure et les systèmes decommunication physiques, les dépenses d&#rsquo;investissement et les coûts de maintenance ont baisséde façon significative», explique M.Fernandez.

Lee Dilworth, responsable EMEA Practice, Storage and Availability, pense que le succès de la HCIs&#rsquo;explique, entre autres raisons, par le fait que les clients veulent changer leur manière de faire. La HCI leur permet en effet de constituer leurs DataCenters sur le principe de l&#rsquo;évolutivité: ils débutent avec les modules dont ils ont besoin à date et auront toute latitude de faire évoluer leur solution dès cela sera nécessaire. En termes de flexibilité, le contraste avec les systèmes de stockage traditionnel, qui supposent un investissement initial conséquent et où tout repose sur le surprovisionnement, estflagrant.

Mais ce n&#rsquo;est pas tout: la simplicité de gestion et de déploiement, la visibilité accrue rendent également la HCI très intéressante, surtout pour les entreprises qui ont besoin de fonctionnalités de DataCenter à distance, parce qu&#rsquo;elle leur fournit un point de gestion central.

Prenons un autre exemple, celui de l&#rsquo;ONO Academic College, la plus grande université d&#rsquo;Israël. Lorsqu&#rsquo;il est devenu nécessaire de remplacer sa baie de stockage, l&#rsquo;établissement a envisagé la HCIpour profiter d&#rsquo;une plus grande flexibilité. Son choix s&#rsquo;est porté sur une solution SSD qui, selon ledirecteur informatique Oren Laufer, a multiplié les performances par vingt, vSAN assurant un excellent service, même sur les sites distants.

«Lorsque nous avons cherché à remplacer notre baie de stockage, nous avons estimé que le concept d&#rsquo;hyperconvergence nous apporterait la flexibilité voulue», explique M.Laufer.

Non seulement la durée des sauvegardes est beaucoup plus courte, mais désormais une seule personne suffit pour gérer l&#rsquo;infrastructure de stockage virtuel, permettant ainsi à l&#rsquo;équipe informatique de consacrer plus de temps au développement de nouvelles applications qu&#rsquo;aux tâches de routine.

Dans ces organisations, et il y en a beaucoup d&#rsquo;autres, VMware facilite la transition vers une solution convergée, avec la perspective d&#rsquo;un ROI rapide. L&#rsquo;impact de la HCI dépasse l&#rsquo;informatique et la technologie. Cette solution permet aux équipes informatiques de se consacrer aux problèmes vraiment importants, elle favorise l&#rsquo;approche DevOps et les programmes de transformation digitale del&#rsquo;entreprise, et elle contribue à la réalisation des objectifs stratégiques.
