企業(yè)的IT策略正迫于壓力做出改變，云計(jì)算在修正方案中變得越來越重要。IDC分析家希望企業(yè)IT商店可以增加私有云方案的實(shí)施。這些云方案中的核心部分往往是存儲。
預(yù)計(jì)2010年至2015年，私有云存儲的花銷將達(dá)到28.9%的年均增長率。照此速度，私有云存儲在2015年前將翻三倍。這比當(dāng)前年均增長為4%的內(nèi)部存儲要巨大。報(bào)告指出，雖然未來四年會看到云服務(wù)收入的巨大增長，但是要求公共云和私有云供應(yīng)商花費(fèi)的資金也同樣巨大。未來四年，私有云與公共云供應(yīng)商預(yù)期成為IT產(chǎn)品花錢最大方的兩大巨頭。
IDC存儲與IT執(zhí)行策略的副董事長Richard Villars編寫的報(bào)告稱：驅(qū)使云存儲增長的主要原因是對“大數(shù)據(jù)”的需求。
Villars 說：“‘云’作為傳遞信息服務(wù)的另一種方式興起將會繼續(xù)成為IT市場改革最重要的開發(fā)之一。存儲產(chǎn)業(yè)有潛力成為這種趨勢下最大受益者，但是供應(yīng)商必須在目標(biāo)存儲、自動分層數(shù)據(jù)、大數(shù)據(jù)處理和高級存檔服務(wù)等領(lǐng)域推動先進(jìn)軟件方案的同時(shí)，均衡云客戶對低成本硬件的增長需求。
IDC報(bào)告引用了企業(yè)贊成內(nèi)部存儲方案云的五大理由：
更高效地向應(yīng)用的互聯(lián)網(wǎng)用戶傳送數(shù)據(jù)或信息。
降低基礎(chǔ)設(shè)施投資成本
抵消存在無法預(yù)測工作的應(yīng)用程序響應(yīng)性
分銷長期信息檔案的成本
使客戶、合作者和機(jī)器生成的大數(shù)據(jù)分析有類持續(xù)性與實(shí)時(shí)性
Villars 說：“未來十年，大數(shù)據(jù)開發(fā)也許是存儲解決方案供應(yīng)商最關(guān)鍵的新市場。提供強(qiáng)大的完整大數(shù)據(jù)解決方案的產(chǎn)品組合——硬件、軟件和實(shí)施服務(wù)——會成為成功的關(guān)鍵因素。同樣，強(qiáng)大的動態(tài)文檔存儲方案會成為私人內(nèi)容/文檔云部署的關(guān)鍵微分器。”
Enterprise IT strategies are under pressure to change, and increasingly the cloud is becoming an important component in revised strategies. Analysts at IDC expect that Enterprise IT shops will increasingly implement private-cloudsolutions. And often the central component of these cloud solutions is storage.
Spending on private-cloud storage is expected to increase at a compound annual growth rate of 28.9 percent from 2010 to 2015. At that rate, private-cloud storage will triple by 2015. That’s huge compared to the growth of on-premise storage which is growing currently at about 4 percent annually. The report notes that while revenues for cloud services will see huge growth over the next four years, the amount of money that public and private cloud providers will be required to spend is equally huge. Private and Public cloud providers are expected to be two of the biggest spenders on IT products over the next four years.
The IDC report, authored by Richard Villars, vice president of Storage and IT Executive Strategies at IDC, says that much of what is driving that growth of cloud-based storage are the demands of “big data“.
Villars said that “the emergence of the ‘cloud’ as an alternative for information services delivery will continue to be one of the most important developments in the evolution of the IT market. The storage industry has the potential to be one of the biggest beneficiaries of this trend, but suppliers must balance growing demands from cloud customers for low-cost hardware while boosting demand for advanced software solutions in areas such as object-based storage, automated data tiering, Big Data processing, and advanced archiving services.”
The IDC report cites five main reasons why enterprises are favoring cloud-based over on-premise storage solutions:
More efficient delivery of data/information to internet-based users of applications.
Lowers infrastructure investment costs
Evens-out the responsiveness of applications that have unpredictable workloads
Distributes the cost of long-term archival of information
Enables near-continuous, real-time analysis of Big Data generated by customers, partners and machines
Villars said that “Big Data developments will be perhaps the most critical new marketplace for storage solutions providers in the coming decade. Providing a strong portfolio of complete Big Data solutions — hardware, software, and implementation services — will be a high priority to succeed. Similarly, a strong portfolio of active archival storage solutions will be a critical differentiator for private content/archive cloud deployments.”
