In our view, a private cloud is a computing environment which provides hosted services to a limited subscriber base, generally within a single enterprise behind a firewall. Private clouds are a conservative’s answer to a regular public cloud solution.  Instead of losing sleep worrying about control, safety and costs of hosting data at a third party vendor’s data center, enterprises build their very own in-company, and mostly in-premises private cloud solution.
The chargeback metering mechanisms are an added plus for the higher management, for they provide a relatively accurate picture of the “cost of IT” in the organization. The hardware (servers and other resources) on the network should be under centralized control and standardized.
There should be very lose coupling across services, effectively allowing services across different environments based on different parameters, transparently.
The infrastructure management and maintenance should be automated, reducing the overall manual dependence and increasing efficiency of the overall system. These items listed above are not really axioms which HAVE to be followed in order to justify an enterprise installation to be a private cloud; however the more of the above list a company follows, a more mature and stable environment is promised.
In 2012, more than 1.7 million jobs in the field of cloud computing remained unoccupied, according to analysts firm IDC. Cloud marketing has the ability to drastically change the ways in which they reach and engage their audience, particularly with regard to distributing and storing mission-critical data. More and more companies encourage their employees to work on their devices, thus reducing the cost of computer equipment, but also increase the cost to maintain licenses and safety.
Despite the inclination to wait until all of the cloud’s kinks have been worked out, holding off on cloud initiatives until the industry matures won’t guarantee success.
The software industry is undergoing major changes by trends such as cloud, SaaS, mobile technology and the “consumerization of IT”. To help out, the government will oftentimes approve these foreign companies to enter the Chinese market. The technology giants move a massive amount of manpower around to whip up a similar offer in a short amount of time.
Of course, the above is a widely generalized, short cut version of the story, although the basic idea is valid. That said, it is too easy to just regard overlooked services or an overload of rules to be caused by a lack of expertise or knowledge, as there is more going on.
I’m going off on a tangent now, but whenever talking about this, I always like to mention payment providers and retail platforms as a fitting illustrating example. When you compare the interfaces, things look mostly the same as well, with Baidu standing out thanks to a black header bar and an uglier font. All three implement support for pictures, video, and music which can be viewed right from the app. Whereas both Dropbox and Google follow the strategy to put most in an accessible web app and offer a small sync client to install on your computer, the Chinese counterparts go all out and offer a wealth of apps — a pattern which is very typical. I mentioned before that in case of things going awry, it doesn’t take long for a fix to be implemented. To close off this post, I’m going to present a little reverse engineering I did to make a hand-rolled Weiyun API. I love this example because it already shows how many limitations and extra flags there are in place. Interestingly, we see that folders are characterized by an MD5-looking key, whereas files have a UUID-looking identifier, as well as MD5 and SHA1 hashes. Note that this command does not only require the folder key you wish to retrieve the listing for, but also its parent. You might think that this explains the reason why there exists separate commands for listing the main directory (as this one has no parent, right?) and other directories. Note that we need to resend our request in case we try with hashes first and the file was not found.
You might recall that these are sent with every request, and do not change during the lifetime of the session. At the time of writing up this post (which took a few days), I noticed that the upload mechanism over at the English version of Weiyuns app became increasingly flaky.
I took a look at the Chinese version to see if things were still working there, and it seems that indeed, it does. Sadly, the underlying classes (MD5Context and friends) in the decompiled Flash source correspond with a custom-made crypto library which is thousands of lines long. IDC expects that spending on cloud IT infrastructure will grow across all regions and all technologies.
Taxonomy Notes:IDC defines cloud services more formally through a checklist of key attributes that an offering must manifest to end users of the service. SummaryIT storage leaders and compliance personnel are likely to compare on-premises and cloud (hosted) archiving solutions, mainly for email. Organizations are struggling with how to meet compliance and regulatory requirements for exploding email repositories, including on-premises and hosted email solutions. Primary email system performance and expensive email storage costs are driving organizations to review options for archiving email. As the term cloud becomes part of the business vernacular, IT leaders need ways to help other business leaders separate hype from fact, and to explain why hosted solutions may or may not be the right fit for their organizations' archiving needs. Understand the advantages and drawbacks of on-premises and cloud approaches for archiving, and map them across your organization's culture and mandates about the location of and access to information. Do a full TCO assessment of on-premises and cloud email archiving solutions, and be sure to consider the factors of upkeep and vendor relationships for a long-term retention system.
IntroductionWhen it's time to choose between on-premises or hosted options, you may find it difficult to blaze a clear path to a decision. When considering your options, focus on identifying your organization's requirements using the five factors depicted in figure below. In terms of traction in the market, inquiries with Gartner clients have shown that email is most often the leading edge of archiving decisions.
Consider the Variety and Types of Data and Information SourcesToday's email archiving solutions are evolving to support multiple content types beyond email, and it's not uncommon to see products and services that support email, SMS, IMs and social media in the same archive repository. Interestingly the fastest-growing data types - such as email (on-premises or hosted), IM, SMS, mobile and social media - are good candidates for hosted archiving. Gartner clients who are moving their archives to the cloud tend to share some characteristics.1 In some instances, companies have a corporate mandate to move anything that can be hosted to the cloud.
Take Into Account Your Organization's Position on SecuritySome organizations operate with a corporate mandate or just a corporate culture of keeping critical business information behind the firewall for reasons of security or control, or otherwise.
Similarly, internal or regulatory requirements may give some organizations a need to ensure that their data is stored within the boundaries of a particular jurisdiction (such as a country or region). If your organization is comfortable with the data security provided by a SaaS solution, include cloud-based services in your review.


Understand Your Employee and Administrative Access RequirementsWill your employees or system administrators require offline access to the archived data?
Many organizations find the administrative and supervisory tools available from cloud email archiving vendors more user-friendly than on-premises tools. The compute infrastructure of hosted archived data solutions can enable faster search and indexing than on-premises solutions, due to the leveraging of that infrastructure build-out by the hosted provider. Assess Staff Capacity and IT InfrastructureAssess the capabilities and capacity of your IT infrastructure and operations (I&O) staff and your IT infrastructure.
First, determine if your existing staff has the skill set and the time required to develop a cost-effective email archiving system that is easy to use for key stakeholders (such as legal and compliance teams). Factor in Price and TCOIn many cases, the cost for hosted email archiving is slightly higher than for a well-oiled on-premises solution, but not prohibitively so. You should also consider the intangible cost of neglect over time, which often arises with archiving implementations.
A PUPM pricing model that could include add-ons, such as social media, Web pages, mobile, e-discovery, etc.
Moving your archive repository from one solution to another can be quite costly, so keep this in mind during the negotiations. File archiving is usually more cost-effective on-premises, because the price for the hosted archiving of data is calculated by capacity and the price for full SaaS solutions hasn't dropped enough to match on-premises pricing. Strategic Planning AsssumptionBy 2016, 80% of organizations will move to a cloud model for enterprise information archiving, up from 30% in 2011. This little-known market timing indicator just gave an unmistakable signal of where the market is headed next! Cloud computing is poised to be the catalyst for this new model, and a new survey by the Business Software Alliance supports this – with their survey revealing that use of cloud computing is highest in Greece and Romania within EU, with Greece garnering a 39%.
Cloud Computing will provide a much needed reduction in IT spending, boost productivity, and create new opportunities for business development in the country. Under baseline assumptions of early adoption, Greek businesses and the public sector can save almost € 5 billion in expenditures.
The overall cloud dividend over the next decade can reach € 16 billion, especially when combined with the spill-over effects from increases in the intermediate demand and household income.
Cloud computing adoption will bring an increase in scalability and a reduction of barriers to entry, and will add € 5 billion of income to the Greek economy within the next decade. Some stop at virtualization, other take it at the automation of the provisioning and elasticity, and some others take it to the final level and talk about chargebacks.
Baidu (search), Taobao, Weixin and QQ for instance are such success-stories.In other cases, however, some services also end up being kept-alive in some sort of zombie state.
Sure, a social network not receiving much love will be down once in a while, and a game might be unable to connect to some server from time to time as well, but no real harm is done and in most cases a team is scrambled to get things running again. Sometimes you get a link which ends up in a ZIP download, sometimes you can add it to your own drive, sometimes you get a barcode, and so on. It is strange that this is included, as the names of the endpoints already differ and indicate which action should be executed. Another strange aspect is the fact that we need to provide a dir_mtime parameter (perhaps it was planned to use this as an extra time based filter?). The JSONP responses look a bit different, which is why we extend the get_response function. If the request succeeds, the server will respond with a 302 (Moved Temporarily) status code which requests will follow through to start downloading the file.
The new request will have no hashes and the upload type set to 1 (we do so by deleting the temporary broken file and calling a new FileUpload instance without hashes). I’ll probably not maintain this for long, but feel free to fork or submit pull requests. At first, I thought this was an issue with my code, but uploading through the site itself also seems to be failing (at least at this moment in time). In addition, I’ve noticed that this version now relies on a Flash helper which performs uploads in the same manner as the Window client does (verified using Wireshark).
This endpoint allows to get a user profile picture for any QQ number, without having to be logged in.
In most regions, growth in public cloud IT infrastructure spending will exceed growth in spending on private cloud IT infrastructure as public cloud service providers will continue to invest in expansion of their datacenters and service offerings.
Spending on public cloud IT infrastructure will grow at a slightly higher rate than spending on private cloud IT infrastructure - at 16.5% vs 14% CAGR. It's two-year old but we didn't publish it and think that it was interesting enough to be published now. Assess each solution's advantages within the context of your organization's requirements in five specific areas. Furthermore, the rise in the popularity of all things cloud may place you under pressure to focus on hosted solutions that might not ultimately be the best fit for your organization's needs. Once you understand how your needs align with the advantages and risks of each offering, it becomes much easier to choose an appropriate system. On-premises and cloud (software as a service [SaaS]) options are more attractive alternatives to personal archives, such as PSTs and other email storage approaches, because organizations have better control of the data for compliance, risk and cost needs.
For example, it's a common approach to archive information that is stored in databases by partitioning the database and moving a small part of it to storage, where it resides in a compressed state.
For example, use typical on-premises archiving to support performance, and use cloud-based services to retain retired data from applications.
We are also seeing companies choose to send all non-mission-critical applications or data to cloud-based archives.
Depending on the vendor's approach, hosted services may or may not be a suitable option for these organizations, but you must understand the vendor's approach to storing data and the jurisdictions within which it operates. However, Gartner has found that email archiving SaaS providers are encrypting data in flight and at rest, with most organizations adhering to Standards for Attestation Engagements (SSAE) 16, International Organization for Standardization (ISO) 27001 and other cloud services standards (see SAS 70 Is Gone, So What Are the Alternatives?). Many of Gartner's clients from the financial services and other highly regulated industries are using hosted email archiving solutions and are comfortable with the level of security of their data.
On-premises email archiving will require more resources than hosted services, and that will add storage and other IT infrastructure on top of an already taxed IT department. Next, decide if these responsibilities are more or less important than the many other competing priorities on which your staff must focus. If your archiving system (email or other) will be connected to other on-premises systems (such as security, storage or e-discovery), then on-premises archiving may deliver better performance results for you and your stakeholders, such as legal and compliance teams.
Systems are not updated, and shortcuts are taken on administration and storage; therefore, access to the data when needed can be more costly than is otherwise necessary.
Very low-cost storage cloud targets that can be used for archived data need to be carefully evaluated, because integration is still complex, as is the maintenance of the cloud as a target.


For instance, the company acquired 5 companies in fiscal 2013 with the most impressive acquisition being that of ExactTarget. The onus of improvement is on the shoulders of both the State and the companies, in order to ensure that a new model of development is born, where private investment and export are the key growth drivers.
Additionally, over 24% of personal computer users in Greece report high levels of familiarity with cloud computing technology. The cloud dividend can reach € 21 billion if Greece manages to outpace their competitors via a 5 year transition path (compared to the average 10 year transition path followed by competing nations).
However, many of these things are done in a very ad-hoc, seemingly chaotic manner which looks confusing, daunting and maybe untrustworthy to outsiders. A vast amount of companies, banks, public service institutions and even restaurants have payment and other support systems in place which all work very well, also on smartphones (the primary computing platform in most of Asia). Apparently there is some sort of hashing going on which compares your file’s hash to other files which have been uploaded to the service. The license is permissive (MIT), and I’d love to hear if this ends up being useful in some way. The public cloud market includes variety of services designed to extend or, in some cases, replace IT infrastructure deployed in corporate datacenters. Prior to joining Gartner, Dayley was at Veritas Software, Novell, Quest Software, Proclarity and 3M. Due to this traction, this best-practice research will use email as the primary use case for archiving decisions. Also, cloud email archiving providers charge on a per user per month (PUPM) basis for services that may include the archiving of additional content types, making cloud email archiving providers an attractive option. If such data is stored in the cloud, it could be a real challenge to give users real-time access to it. This approach is becoming more common, as well over 50% of the conversations with customers around email archiving include cloud options. Explain your organization's position to prospective vendors to determine if their offerings are a match for your needs. Many of the hosted email archiving solutions allow you to cache the email archive, whereas files and other archived data types may only be available while connected online. However, retrieval is often done for discovery purposes or other reasons that don't require immediate access, and usually not as time sensitive as, for example, with primary or backup storage. Additionally, a recent report by the IOBE posits that early adoption of cloud technology will play a crucial role in the competitiveness of the Greek economy. However, if technophobia prevails and slows down the rate of adoption, the cloud dividend will only extend to about € 5 billion and will show very little or no employment gains during the next 6 to 7 years. Baidu’s Baike was supposed to be a Wikipedia clone and has surpassed the latter in terms of articles (for the Chinese Wikipedia, that is), but is lacking in terms of interface and infrastructure, and less curated, with less useful or inaccurate articles as a result [2]. Privacy concerns are crucial, but failure is possible, leading to a big PR scandal, as users are very sensitive to this. PIN codes are 6 digits, logins are verified with a text message or a QR code (those which were all the rage in western territories for a while and then mostly died out due to lack of adaption). When a match is found, the cloud service can make the file appear in your drive without actually having to upload the file.
Even if the current user does not yet have the file in question, the hash matching is performed for every file on the system.
Next however, a series of POST requests is made which seem to upload chunks of the file to be uploaded with some magic header stuck in the front.
It also includes content services delivered by a group of suppliers IDC calls Value Added Content Providers (VACP).
If you plan to archive sizable data stores, recognize that the cost of moving that information across the wire could be quite high. Conversely, some critical information sources are more appropriate for on-premises archives.
We only expect this to increase so that, by 2016, 80% of organizations will use the cloud for at least part of their data archiving needs. The company provides a customer and collaboration relationship management (CRM), applications through the Internet or cloud. Of course, users get hacked, scammed, or tricked all the time, but this is mainly caused by the massive scale (more targets) and again is easy to mistake for a lack of efficiency (also again since everything kind of seems to be set up in a chaotic, intertwined and rather ad-hoc manner). You can upload folders however through a separate drop down and selecting the folder, but not if the folder contains sub folders.
I’ve tested this extensively with Weiyun (more on this below), and the matching works even when you delete the file afterwards, and can allow you to add files even if you do not have the actual file. If the file is not found (or not hashes are provided), the server will provide a location to which we can upload the file by a following POST (strangely enough, uploading with requests streaming behavior does not seem to work right, as the server closes the connection prematurely). Most vendors do not currently offer WAN optimization or gateway technologies to assist in archived data movement. These information sources - which could include file servers, integrated databases and custom enterprise applications - often lend themselves better to on-premises archives. Also, cloud archive vendors provide quality integration between the on-premises applications and the cloud-archived data. Cloud computing refers to the use of Internet-based computing, storage and connectivity technology to deliver a variety of different services. Sure, you can expect a fair share of self-signed SSL certificates or the government snooping in, but these are mainly caused by a more-rules-is-always-better culture and the lack of concern for privacy. Data can be moved from on-premises to the cloud and vice versa via shipping physical disks or tape, but that adds to the cost and complexity, and introduces the opportunity for error.
Not in itself, but just be aware of the fact that no encryption is happening anywhere (Dropbox used to apply similar techniques but then toned it down due to user complaints). Larger data stores might also make hosted services cost-prohibitive if the pricing is calculated on a capacity basis.
For more great stories in this context, look for instance at the way how Bitcoin has been adopted (and pushed out) in China, complete with mining factories, really. Folder dragging is only supported by Webkit (Chrome) at the moment, but it still seems strange that no more middleware libraries such as filedropjs are used which already take this into account.
