Le TCO des Clouds Publics est-il toujours inférieur à celui des centres de calcul privés ?

 

Saugatuck-logo_02J’ai souvent cité dans ce blog les travaux, très sérieux, de la société d’études de marché Saugatuck, dirigée par mon ami Bill McNee, qui sont pour l’essentiel consacrés aux infrastructures Cloud et aux usages SaaS, Software as a Service.

Dans ce billet, je fais référence à l’une de leurs dernières études, qui analyse avec précision le TCO (Coût Total de Possession) des solutions d’infrastructures gérées en interne vis-à-vis des solutions externalisées.

Pourquoi ? Les études quantitatives sur ces sujets sont rares, et j’entends trop souvent des discours théoriques sur ces sujets, qui ne sont pas basés sur des mesures précises.

 

L’étude de Saugatuck

  Understanding Cloud Infrastructures costsPour faire le point sur le TCO des infrastructures serveurs, Saugatuck vient de publier une analyse comparative détaillée des offres de trois «Clouds publics, IBM, Rackspace et Dimension Data.

Saugatuck, comme toutes les sociétés d’étude, commercialise ses rapports, soit sous forme d’abonnement annuel, soit à la carte, la première formule étant rapidement plus avantageuse.

Je ne peux donc pas donner ici tous les résultats, mais il y a des informations que j’espère utiles que je peux donner dans ce blog.

 

Le modèle d’analyse utilisé pour la demande

Dans ce document de 13 pages, très analytique, Saugatuck a identifié trois variables principales pour l’entreprise qui envisage de migrer tout ou partie de ses applications sur un Cloud Pubilc :

  • Le niveau d’efficience des centres de calcul privés. En prenant comme référence les centres de calcul les plus efficients en termes de performances et de couts, Saugatuck utilise trois niveaux différents :
  • Efficience maximale.
  • 20 % de perte d’efficience.
  • 50 % de pertes d’efficience.

Saugatuck cost small workloadDans ses mesures, Saugatuck a trouvé que seules quelques très grandes entreprises peuvent atteindre l’efficience maximale. Les grandes entreprises sont dans les zones - 20 % à - 50 % et les petites et moyennes dans la zone des - 50%. Cette étude confirme que les économies d’échelle liées à la taille sont une réalité.

Sur le tableau simplifié que j’ai extrait de ce rapport, le coût mensuel en interne, pour les situations optimales est d’environ 1 000 dollars pour une charge de travail de petite taille (voir ci-dessous).

  • La nature des charges de travail à transférer. Les trois composants, partie Web, Application et base de données utilisée, ainsi que leur variabilité dans le temps sont les principaux critères à prendre en considération. Sans surprises, la rentabilité des clouds publics s’accroit avec la variabilité de la charge dans le temps, les applications ayant des pointes importantes étant celles qui profitent le plus des clouds publics.
  • Saugatuck Small workload

 

 

  • La taille des charges de travail à transférer. Saugatuck a défini trois niveaux de taille pour les applications, le plus souvent mesurés en nombre de machines virtuelles nécessaires. Comme on le verra plus loin, plus la charge de travail est légère, plus les clouds publics sont rentables.
  •  

    L’analyse comparative des offres de cloud public

    Logos IBM Dimension, RackspaceLes tableaux de synthèse comparent les coûts des infrastructures d’un centre de calcul privé avec ceux de Dimension Data, IBM et Rackspace.

    Deux remarques :

    • Les différences de coûts entre les fournisseurs de Cloud publics sont très significatives et peuvent atteindre un rapport de 1 à 2 dans certains cas.
    • Les entreprises clientes ont intérêt à comparer les offres et faire jouer la concurrence pour accroître les réductions de coûts potentielles.
    • Dans la majorité des cas analysés, Dimension Data est le fournisseur le plus agressif en termes de prix, suivi par Rackspace, IBM étant souvent le plus cher des trois.

    Je regrette un peu que le leader incontesté des infrastructures Cloud, Amazon Web Services, n’est pas été inclus das cette étude, qui privilégie les fournisseurs ayant plus une culture «hébergeurs» que IaaS, Infrastructures as a Service.

     

    Quelques résultats de cette étude

    TCO La synthèse tient en une phrase :

    «Our bottom line? Cloud resource use makes terrific sense to help reduce enterprise IT costs – when Cloud is used in the right way(s) for the right workloads.»

    (L’utilisation des ressources du Cloud a énormément de valeur pour aider les entreprises à réduire leurs coûts informatiques - quand elles sont utilisées à bon escient et pour des charges de travail adaptées).

    Les fourchettes de bénéfices que l’on peut attendre d’un portage d’une charge de travail informatique peuvent varier :

    • De 5 % à près de 70 % pour les charges légères.
    • De 10 % à près de 40 % pour les charges moyennes.
    • De 5 à environ 20 % pour les charges importantes.

    Cette étude démontre aussi que dans les rares cas de très grandes entreprises qui gèrent exceptionnellement bien leurs centres de calcul privés, basculer sur des clouds publics pour des applications utilisées massivement, peut... augmenter le TCO de ces applications.

    En résumé :

    Sushi private cloud

    • Les très grandes entreprises qui gèrent exceptionnellement bien leurs centres de calcul privés doivent faire une analyse préalable de leurs usages informatiques pour déterminer les activités qu’il conviendrait de garder en interne.
    • Pour toutes les entreprises, petites, moyennes et grandes et pour les très grandes, mais gérant «normalement» leurs centres de calcul privés, les solutions Cloud Publics, proposées par les acteurs les plus compétitifs auront toujours un TCO plus bas.
    • Les différences de coûts entre les fournisseurs de clouds publics sont suffisamment fortes pour que ce qu’il est rentable de confier à l’un ne le soit plus pour un autre.

    One of the biggest challenges when developing connected devices is identifying user value and delivering it through successful user experiences. In his session at Internet of @ThingsExpo, Mike Kuniavsky, Principal Scientist, Innovation Services at PARC, described an IoT-specific approach to user experience design that combines approaches from interaction design, industrial design and service design to create experiences that go beyond simple connected gadgets to create lasting, multi-device experiences grounded in people's real needs and desires.
    We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
    The Internet of Things will greatly expand the opportunities for data collection and new business models driven off of that data. In her session at @ThingsExpo, Esmeralda Swartz, CMO of MetraTech, discussed how for this to be effective you not only need to have infrastructure and operational models capable of utilizing this new phenomenon, but increasingly service providers will need to convince a skeptical public to participate. Get ready to show them the money!

    Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
    The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...

    The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...
    Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...
    Explosive growth in connected devices. Enormous amounts of data for collection and analysis. Critical use of data for split-second decision making and actionable information.

    The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs.
