Paracatu (depois não digam que não avisei) Há um tempo publiquei um post a respeito sobre o surgimentos das “clouds” para todos os lados. E um dos reflexos disso são situações, como dessa reportagem da CIO: “Adoção desregrada de cloud preocupa executivos”.
Vou diretamente ao ponto relevante na reportagem sobre esse assunto “… Recente estudo da Avanade revela: um em cada cinco executivos diz ser impossível gerir a grande variedade de serviços de cloud computing disponíveis nas suas organizações …”.
Por isso, avalie, e muito, a empresa que esteja oferecendo algo na nuvem, mesmo que seja um sorvete. A possibilidade de o sabiá ser um pardal pintado com guache é enorme.

Araraquara (bad news). Uma dos grandes questionamentos que são feitos quando uma empresa adota uma solução SaaS, ou qualquer outra solução de cloud computing, é sobre a disponibilidade e qualidade do serviço. A Microsoft tem trabalhado com uma qualidade exemplar no BPOS, até ontem. Nós da América do Sul estamos sofrendo com problemas no Exchange Online desde ontem. Esse é o relato do health dashboard, com as respectivas informações:
Visão geral dos serviços que estão com problemas.
Problemas com o OWA aparentemente sanados.
Fluxo de e-mail no Exchange: a Microsoft está trabalhando, mas a situação ainda não está 100% normalizada.
Vamos esperar e ver qual será os próximos passos dados para a solução do problema. O twitter do time de serviços online, @msonline, já enviou um pedido de desculpas sobre o problema.
Informações sobre o problema disponibilizadas pelo twitter do @msonline.
De acordo com eles, a causa do problema já foi solucionada, mas a fila para entrega das mensagens ainda é grande. O twitter recomenda que seja monitorado o helth dashboard para novas informações.
Esse é o ponto quando falamos de cloud computing: tudo vai bem quando a carga ou o volume que o serviço trata é moderado. Mas agora que o Exchange Online cada vez mais está sendo utilizado é a hora que a Microsoft deverá provar que tem uma ótima infraestrutura e suporte para SaaS. Particularmente, continuo acreditando que sim.
É esperar para ver.
22:55 – Atualizando:
O pessoal do Time de Serviços Online solucionou o problema. Segue os trechos mais importantes no health dashboard:

Description
8:45 PM 
The BPOS Operations team has resolved the problem affecting Exchange Online mail flow for customers served from this region. All mail queues are fully drained and all mail flow has returned to normal. The team will provide a full post mortem of this incident and also will provide final updates on how our service level agreement (SLA) was impacted.
8:07 PM 
The BPOS Operations team continues to monitor email flow in the environment. 90% of email queues have drained and new email is being sent and received without delays. Next update will be within one hour or when new information is available.
7:12 PM

6:12 PM
This is a short update on work underway to resolve problems that have occurred with the Exchange Online Service on May 12 2011 and the actions that the team is taking to resolve these problems. Starting at 9:10am PDT, service monitoring detected malformed email traffic on the service. This malformed email traffic resulted in problems sending and receiving email until 10:03am PDT, when the problem was rectified. The offending mail was removed from the service, and service restored. Email was delayed by ~45minutes during this time. A second issue was detected via monitoring at 11:35am PDT, with email stuck in end users outboxes. The issue was remediated at 12:04pm PDT. During this time, more than 1.5 million messages had queued on the service awaiting delivery. This email is now flowing through the system, however because of this large volume of email; we are experiencing delays of as long as 3 hours. The team continues to work to fully resolve the issue, and will provide a full post mortem of this incident following service restoration, and also will provide additional updates on how our service level agreement (SLA) was impacted.
5:12 PM 
The BPOS Operations team continues to monitor email flow in the environment. Email queues continue to drain, but we still see delays of up to 3 hours based on the significant amount of email that is queued. Next update will be within one hour or when new information is available.
4:19 PM
The BPOS Operations team continues to monitor email flow in the environment. The team has resolved issues with users seeing email stuck in draft or outbox. Users with mail that was previously queued in their outbox may see delays of up to 3 hours for final delivery based on the significant amount of email that is queued. Microsoft is closely monitoring the situation and expects mail queues to reduce to normal levels in the next several hours. Next update will be within one hour or when new information is available.
Nesse informativo, vejo uma informação importantíssima: será informado como o SLA foi afetado. Vamos aguardar essas informações e ver quais serão os próximos passos após esses problemas.

Ribeirão Preto (sem pressa!). E assim, mais uma onda na TI avança …
Araraquara (Belo dia! Perfeito para um Chopp). Principalmente para os iniciantes em TI, surge sempre aquela pergunta bem simples: “Mas o que é essa tal de Cloud Computing?”. Como já fizeram isso, compartilho com vocês esse artigo da Cloud Computing Journal com vinte e uma definições sobre Cloud Computing. Eu já escolhi a minha preferida. E vocês?
It is the infrastructural paradigm shift that is sweeping across the Enterprise IT world, but how is it best defined?
It is the infrastructural paradigm shift that is sweeping across the Enterprise IT world, but how is it best defined? I refer of course to ‘Cloud Computing’ – the phenomenon that currently has as many definitions as there are squares on a chess-board. To try and narrow it down we bring here a round-up of some recent attempts to bring welcome precision where there risks being unnecessary vagueness. Enjoy!
"What is cloud computing all about? Amazon has coined the word “elasticity” which gives a good idea about the key features: you can scale your infrastructure on demand within minutes or even seconds, instead of days or weeks, thereby avoiding under-utilization (idle servers) and over-utilization (blue screen) of in-house resources. With monitoring and increasing automation of resource provisioning we might one day wake up in a world where we don’t have to care about scaling our Web applications because they can do it alone."
–Markus Klems
"For me the simplest explanation for cloud computing is describing it as, ‘internet centric software.’ This new cloud computing software model is a shift from the traditional single tenant approach to software development to that of a scalable, multi-tenant, multi-platform, multi-network, and global. This could be as simple as your web based email service or as complex as a globally distributed load balanced content delivery environment.
I think drawing a distinction on whether its, PaaS, SaaS, HaaS is completely secondary, ultimately all these approaches are attempting to solve the same problems (scale). As software transitions from a traditional desktop deployment model to that of a network & data centric one, "the cloud" will be the key way in which you develop, deploy and manage applications in this new computing paradigm."
– Reuven Cohen
"I view cloud computing as a broad array of web-based services aimed at allowing users to obtain a wide range of functional capabilities on a ‘pay-as-you-go’ basis that previously required tremendous hardware/software investments and professional skills to acquire. Cloud computing is the realization of the earlier ideals of utility computing without the technical complexities or complicated deployment worries."
– Jeff Kaplan
"People are coming to grips with Virtualization and how it reshapes IT, creates service and software based models, and in many ways changes a lot of the physical layer we are used to. Clouds will be the next transformation over the next several years, building off of the software models that virtualization enabled."
– Douglas Gourlay
"The way I understand it, “cloud computing” refers to the bigger picture…basically the broad concept of using the internet to allow people to access technology-enabled services. According to Gartner, those services must be ‘massively scalable’ to qualify as true ‘cloud computing’. So according to that definition, every time I log into Facebook, or search for flights online, I am taking advantage of cloud computing."
– Praising Gaw
"The “Cloud” concept is finally wrapping peoples’ minds around what is possible when you leverage web-scale infrastructure (application and physical) in an on-demand way. “Managed Services”, “ASP”, “Grid Computing”, “Software as a Service”, “Platform as a Service”, “Anything as a Service”… all terms that couldn’t get it done. Call it a “Cloud” and everyone goes bonkers. Go figure."
– Damon Edwards
"There sure is a lot of confusion when it comes to talking about cloud computing. Yet, it does not need to be so complicated. There really are only three types of services that are cloud based: SaaS, PaaS, and Cloud Computing Platforms. I am not sure being massively scalable is a requirement to fit into any one category."
– Brian de Haaff
"SaaS is one consumer facing usage of cloud computing. While it’s something of a semantic discussion it is important for people inside to have an understanding of what it all means. Put simply cloud computing is the infrastructural paradigm shift that enables the ascension of SaaS."
– Ben Kepes
"The ‘cloud’ model initially has focused on making the hardware layer consumable as on-demand compute and storage capacity. This is an important first step, but for companies to harness the power of the cloud, complete application infrastructure needs to be easily configured, deployed, dynamically-scaled and managed in these virtualized hardware environments."
– Kirill Sheynkman
"I was chatting with a customer the other day who was struggling with some of the implications of cloud computing. The analogy that finally made sense to them is what I will call ‘cloud dining.’ I am the cook in the house and I am tasked with feeding the family. If my 10-year old is lobbying for Italian, I am cook at home or order out. The decision may also vary from day to day. For instance, I might not have all the ingredients and have to order out, or, like this weekend, it may be 103 outside and cooking at home is not all that appealing. Now, the same can be said for supporting a given application in a cloud computing environment.
In a fully implemented Data Center 3.0 environment, you can decide if an app is run locally (cook at home), in someone else’s data center (take-out) and you can change your mind on the fly in case you are short on data center resources (pantry is empty) or you having environmental/facilities issues (too hot to cook). In fact, with automation, a lot of this can can be done with policy and real-time triggers. For example, during month end processing, you might always shift non-critical apps offsite, or if you pass a certain cooling threshold, you might ship certain processing offsite."
– Omar Sultan
"Cloud computing overlaps some of the concepts of distributed, grid and utility computing, however it does have its own meaning if contextually used correctly. Cloud computing really is accessing resources and services needed to perform functions with dynamically changing needs. An application or service developer requests access from the cloud rather than a specific endpoint or named resource. What goes on in the cloud manages multiple infrastructures across multiple organizations and consists of one or more frameworks overlaid on top of the infrastructures tying them together. The cloud is a virtualization of resources that maintains and manages itself."
– Kevin Hartig
"Clouds are vast resource pools with on-demand resource allocation. The degree of on-demandness can vary from phone calls to web forms to actual APIs that directly requisition servers. I tend to consider slow forms of requisitioning to be more like traditional datacenters, and the quicker ones to be more cloudy. A public facing API is a must for true clouds.
Clouds are virtualized. On-demand requisitioning implies the ability to dynamically resize resource allocation or moving customers from one physical server to another transparently. This is all difficult or impossible without virtualization.
Clouds tend to be priced like utilities (hourly, rather than per-resource), and I think we’ll see this model catching on more and more as computing resources become as cheap and ubiquitous as water, electricity, and gas (well, maybe not gas). However, I think this is a trend, not a requirement. You can certainly have clouds that are priced like pizza, per slice."
– Jan Pritzker
"Cloud computing is … the user-friendly version of grid computing."
– Trevor Doerksen
"Most computer savvy folks actually have a pretty good idea of what the term "cloud computing" means: outsourced, pay-as-you-go, on-demand, somewhere in the Internet, etc."
– Thorsten von Eicken
"In order to discuss some of the issues surrounding The Cloud concept, I think it is important to place it in historical context. Looking at the Cloud’s forerunners, and the problems they encountered, gives us the reference points to guide us through the challenges it needs to overcome before it is adopted."
– Paul Wallis
"I would like to propose a ‘Cloud Pyramid’ to help differentiate the various Cloud offerings out there. [At the top of the pyramind] users are truly restricted to only what the application is and can do. Some of the notable companies here are the public email providers (Gmail, Hotmail, Quicken Online, etc.). Almost any Software as a Service (SaaS) provider can be lumped into this group.
As you move further down the pyramid, you gain increased flexibility and control but your a still fairly restricted to what you can and cannot do. Within this Category things get more complicated to achieve. Products and companies like Google App Engine, Heroku, Mosso, Engine Yard, Joyent or force.com (SalesForce platform) fall into this segment.
At the bottom of the pyramid are the infrastructure providers like Amazon’s EC2, GoGrid, RightScale and Linode. Companies providing infrastructure enable Cloud Platforms and Cloud Applications. Most companies within this segment operate their own infrastructure, allowing them to provide more features, services and control than others within the pyramid."
– Michael Sheehan
"The web fanatics and blogosphere would have you believe that all applications will move to the web. Some will, most will not. Reliability, scalability, security, and a host of other issues will prevent most businesses from moving their mission critical applications to hosted services or cloud based services. The risk of failure is too great.
Amazon is the leader in cloud based services, but even Amazon has experienced down times for its own business. Cloud services will continue to improve. But my guess is the uptake will take longer than most people predict."
– Don Dodge
"Today’s combination of high-speed networks, sophisticated PC graphics processors, and fast, inexpensive servers and disk storage has tilted engineers toward housing more computing in data centers. In the earlier part of this decade, researchers espoused a similar, centralized approach called "grid computing." But cloud computing projects are more powerful and crash-proof than grid systems developed even in recent years."
– Aaron Ricadela
"When virtualizing applications to be used by people who care nothing about computers or technology – as is mostly the case with Clouds – the key thing we want to virtualize or hide from the user is complexity. Most people want to deal with an application or a service, not software. … The more intelligent we want [computers and computer applications] to be – that is, intuitive, exhibiting common sense and not making us have to constantly take care of them – the more smart software it will take. But with cloud computing, our expectation is that all that software will be virtualized or hidden from us and taken care of by systems and/or professionals that are somewhere else – out there in The Cloud."
– Irving Wladawsky Berger
"I view cloud computing as a broad array of web-based services aimed at allowing users to obtain a wide range of functional capabilities on a ‘pay-as-you-go’ basis that previously required tremendous hardware/software investments and professional skills to acquire. Cloud computing is the realization of the earlier ideals of utility computing without the technical complexities or complicated deployment worries."
– Ben Kepes
"Cloud computing really comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT’s existing capabilities."

Araraquara (100% adaptado!) ONE COMMENT: Ainda acho que está longe de ser suficiente, mas já é alguma coisa.
Matéria da ComputerWorld em http://www.computerworld.com/s/article/9215461/IEEE_hopes_to_drive_cloud_computing_standards
By Mikael Ricknäs
April 4, 2011 08:41 AM ET
IDG News Service – Standards organization IEEE has decided to get involved in cloud computing, starting with two development projects related to cloud interoperability, it said on Monday.
The current state of cloud computing is comparable to the nascent Internet, according to IEEE (Institute of Electrical and Electronics Engineers). Cloud computing is primed for explosive growth, but "without a flexible, common framework for interoperability, innovation could become stifled, leaving [users] with a siloed ecosystem," the organization warns in a statement.
As part of its cloud push, IEEE has started two working groups, P2301 and P2302, which will look at a wide variety of areas. The P2301 Work Group will work on standardizing cloud portability and management, using a number of file formats and interfaces. While the P2302 Work Group will focus on cloud-to-cloud interoperability and federation. It will, for example, work on standardizing gateways that can handle data exchange between clouds.
In general, standardization in the cloud computing area is an extremely good thing, because it will allow enterprises to use cloud computing more effectively and with more confidence, David Bradshaw, research manager of European SaaS and cloud services at IDC.
However, since cloud computing is still in its infancy, there is also a risk that defining how things should work in detail could have an opposite effect and stifle innovation, according to Bradshaw.
A plethora of organizations are working to standardize cloud computing. Even the European Commission has gotten involved.
Bradshaw said the hope is that they all have the good sense to work together and avoid different islands of standards. The platform level is the area where the need for standardization is most urgent, allowing companies to move workloads from one cloud vendor to another, he said.
The IEEE’s Cloud Computing Initiative is chaired by EMC’s Steve Diamond and the working groups are chaired by David Bernstein, managing director at the consultancy firm Cloud Strategy Partners.

Ribeirão Preto (no ar, eu acho…). É engraçado notar os comportamentos dos fabricantes e das empresas de TI, sempre que uma onda sobre uma determinada tecnologia surge. Todos começam a dizer que fazem rapidinho! E no caso de computação na nuvem ou cloud computing, como queiram, o mesmo aconteceu. Muitas páginas de empresas que já trabalhavam com soluções de hospedagens ou que estavam relacionadas com o oferecimento de serviços na Internet, simplesmente colocaram o slogan que “estão na nuvem”.
Isso me irrita! Agora todo mundo está na nuvem! As mesmas empresas que oferecem um serviço que os usuários/empresas reclamam, com baixa qualidade, com quedas e “downtimes” intermináveis, não respeitando os seus respectivos “SLAs”, agora não estão mais servindo “hosting”, “colocation” ou “e-mail”. Agora estão oferecendo “public cloud”, “private cloud” e “SaaS”. E sem mudar nada. Tudo igualzinho, inclusive a péssima qualidade dos serviços oferecidos. O lance é: “Põe cloud no nome que vende!”. Infelizmente, temos que lidar com essas situações complicadas na área de TI.
Isso me lembra muito a bolha das empresas “.com”, no final dos anos 90 e início de 2000. Não que a nuvem seja uma bolha, mas essa banalização do termo ou da tecnologia pode ser sim. No meu humilde entender, quando uma empresa escolhe a troca de um serviço “on-premises” para um serviço na nuvem, os fatores que ela esta buscando é exatamente qualidade, disponibilidade, segurança, confidencialidade, redundância (geográfica claro) a um preço muito mais vantajoso e com a entrega desse serviço com melhor qualidade, respeitando os “SLAs”, sem reduzir a usabilidade ou a experiência do usuário final. Muito pelo contrário, o que ela que é melhorar isso.
E tudo isso auditado e com políticas de privacidade bem definidas. E com as regras do jogo claras sobre quando uma informação poderá ser acessada por um terceiro, por exemplo, o governo. Ah, e sem esquecer a questão de uma “subida para nuvem” de forma transparente, segura, sem traumas. Com base nisso, o cidadão escolhe ou não ir para a nuvem. Simples? De forma alguma! Por isso, tome muito cuidado na escolha.
Mas enfim, temos o livre arbítrio. Portanto, cuidado com o que oferecem de nuvem para a sua organização, porque no fundo, pode se tratar daquele mesmo serviço ruim, em uma infraestrutura de galinheiro, mas com uma bela maquiagem, e é claro, e um nome “something cloud”. Aí, a “cloud” provavelmente vai ser uma decepção. E pode custar a sua cabeça!
Abraços,
Carlos Monteiro.
Ribeirão Preto (tô entrando no ritmo) O IDGNow trouxe uma excelente reportagem sobre quais são as questões mais importantes que as empresas devem considerar, quando estão estudando a possibilidade de implantar soluções baseadas em Cloud Computing. Obviamente, a reportagem está baseada em uma solução de Cloud Computing para o e-mail, onde tudo fica bem mais claro, já que estamos tratando de um SaaS típico.
O link está aqui. As questões que são abordadas na reportagem são:
– Realizar um levantamento completo das necessidades dos usuários;
– Mapear as integrações do email a outros serviços;
– Fazer uma comparação de custos;
– Verificar que regulamentações legais regem o armazenamento de emails no segmento de atuação da empresa.
Já os passos para o sucesso, sugeridos pela reportagem, são:
1. Arrume a casa;
2. Otimizar a largura de banda;
3. Definir o que será movido;
4. Traçar um plano de ação;
5. Use a imaginação;
6. Sempre tenha um plano “B”.
Creio que não é suficiente, pois questões importantes como disponibilidade, backup e segurança física, que a nuvem teoricamente oferece (já que isso depende de quem está vendendo a solução), não são abordadas pelas reportagem. Se formos considerar PaaS e IaaS, nem se fala. Mas é um começo.
Confiram!
Abraços,
Carlos Monteiro.
Foi publicado em 29/11/2010 um excelente documento sobre privacidade na nuvem. O documento chama-se “Privacy in the Cloud: A Microsoft Perspective”. Ele aborda exatamente o que a Microsoft pensa sobre privacidade nas aplicações que rodam na nuvem.
É uma leitura obrigatória para quem saber sobre as “arestas” de colocar os seus dados na nuvem, e como a Microsoft irá ajudar a protegê-lo e mantê-lo seguro. O paper engloba tudo sobre Private Cloud, Public Cloud, Hybrids, SaaS, Paas, IaaS e como a Microsoft irá abordar as questões sobre privacidade, considerando as fronteiras Internacionais.
O link para download do documento é esse http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d9e313ab-e3cd-490b-9c54-f6626abf63b3
