We often hear that security and privacy concerns are the main inhibitors to cloud adoption. But what are the true threats? Is the cloud really more dangerous than your on-site data center? I would say that virtualization and cloud computing aren’t inherently more dangerous, but they have unique infrastructure that must be addressed when creating a security foundation.
There are similar attacks across physical, virtual, and cloud infrastructures—data-stealing malware, web threats, spam, phishing, bots, etc. So many companies are tempted to deploy their security for dedicated physical...

In my last blog post, I discussed some of the benefits of agentless security for virtual and private cloud servers. Today at VMworld, Harish Agastya, Director of Data Center Security at Trend Micro, conducted a presentation on Agentless Security for VMware Environments (listed on the Trend Micro VMworld page). Trend Micro released agentless antivirus in Deep Security at last year’s VMworld and has seen impressive results over the last year. With such success, today Trend Micro announced an extension of its agentless security with new agentless file integrity monitoring (FIM) in Deep Security...

How difficult is it to run a public cloud service?
As all of us know, Amazon Web Services (AWS) experienced an outage on 21-Apr-2011 and that lasted for almost 4 days. Quite a lot of companies were affected and you can find the list here. The Internet was flooded with articles speculating what went wrong, whether cloud computing is viable in the long run, how Amazon services did not function as advertised, how the applications should be built, etc. While most offered their opinion in broad strokes such as “use multiple regions/clouds”, “use built-in redundancy”, “don’t use public clouds”,...

Last Thursday, April 21, 2011 Amazon Web Services Elastic Compute Cloud (EC2) had an outage that impacted multiple Availability Zones. Thursday morning, Amazon issued a status update indicating that the outage was based on problems with replication mirroring: “This re-mirroring created a shortage of capacity in one of the US-EAST-1 Availability Zones, which impacted new EBS volume creation as well as the pace with which we could re-mirror and recover affected EBS volumes. Additionally, one of our internal control planes for EBS has become inundated such that it’s difficult to create new...

The Small Business Journey to the Cloud is Actually a Round Trip
By Greg Boyle, Trend Micro Global Product Marketing Manager
Many small businesses are still uncertain about cloud computing. They wonder if it can help with their profitability without being extremely risky. Let’s start by defining cloud computing in small business terms. There are two commonly agreed upon types of cloud computing: 1) software-as-a-service and 2) infrastructure-as-a-service.
Software-as-a-service (SaaS) is cloud computing where the software you would normally install on your computers in the office is instead...

Not long ago, we set out on a mission to perform a full scalability test on one of our products (Trend Micro Deep Security). After some quick, back-of-the-napkin calculations we discovered that we needed somewhere in the order of 35 Dell 710′s with virtualization to complete our test. Finding that many available servers is a tall order for any company, and buying that many servers for a month long test was completely out of the question (try asking your managers for 35 servers and see how pale they go!).
Naturally we turned to the cloud to help us out. Amazon Web Services (AWS) was a good...

Amazon Web Services today announced the availability of dedicated compute instances within a VPC:
Dedicated Instances are Amazon EC2 instances launched within your Amazon Virtual Private Cloud (Amazon VPC) that run hardware dedicated to a single customer. Dedicated Instances let you take full advantage of the benefits of Amazon VPC and the AWS cloud – on-demand elastic provisioning, pay only for what you use, and a private, isolated virtual network, all while ensuring that your Amazon EC2 compute instances will be isolated at the hardware level.
Of course, the humor here is that Amazon didn’t...

Do you know what cloudbursting is? It is a concept where when you run out of your computing resources in your internal data center, you “burst” the additional workload to an external cloud on an on-demand basis. The internal computing resource is the “Private Cloud” and the external cloud is typically a “public cloud” for which the organization gets charged on a pay-per-use basis. When your deployment has the ability to do “cloudbursting” or spreading the load to the public cloud, you essentially have a Hybrid Cloud.
Hybrid Clouds can deliver a bit...

One of the delivery models of Cloud Computing is Platform-as-a-Service. In its true definition, a PaaS provider takes care of the underlying infrastructure including the VMs, OS patches, elasticity, auto-scaling, firewalling, etc and provides an API — and a language runtime — to which the programmer should write the code. The users of PaaS have no control over the underlying infrastructure, i.e. there is nothing “open” about it. The most prominent PaaS offerings are Force.com from Salesforce (Apex), Google App Engine (Python and Java), and Microsoft Azure (.NET). It is obvious...

Is Virtualization stupid? It forces guest VMs sharing a host to do the same things over and over, without sharing. It takes up countless hours of otherwise useful – and expensive – server time. Sure, it’s better to consolidate servers using virtualization than to leave them on separate hardware, but it’s still just plain wasteful when dozens of VMs on a single server suck CPU cycles to do the same things their neighbors are doing.
Why do we allow this? For security and flexibility reasons. The predecessor of desktop virtualization was the Citrix Presentation Server, which...
