The article, Visibility in the cloud, provides a general discussion of how to monitor cloud infrastructure. There are a number of APIs and tools available for managing large cloud server deployments in the Rackspace cloud.
By default, Rackspace creates Linux cloud servers with a restrictive firewall configuration. An advantage of using the sFlow standard for server monitoring is that it provides a multi-vendor solution.
In addition, the top servers page, shown below, provides a real-time view comparing the performance of the busiest servers in the cluster. In addition to monitoring server and network performance, sFlow can also be used to monitor performance of the scale-out applications that are typically deployed in the cloud, including: web farms, memcached and membase clusters.
The sFlow push model is much more efficient than typical monitoring architectures that require the management system to periodically poll servers for statistics. Finally, sFlow provides the detailed, real-time, visibility into network, server and application performance needed to manage performance and control costs.
Cluster performance metrics describes how to use sFlow-RT to calculate metrics and post them to Graphite . The sflowtool command line utility is used to convert standard sFlow records into a variety of different formats.
The Graphite realtime charting software provides a flexible way to store and plot time series data.
In order to optimize the performance, security and scalability of your infrastructure, it is critical to have the right compute platform supporting each element of your hosted solution.
Rackspace offers a complete portfolio of compute platforms as well as Hybrid Hosting to make them all work together seamlessly. Hybrid Hosting means you get the best of both worlds: Dedicated Hosting for mission-critical applications, plus the flexibility and fast provisioning delivered by the Cloud. Whether you require Dedicated Servers and Cloud Servers operating independently for different workloads, or a seamlessly integrated architecture for bursting extra compute cycles, Rackspace Hybrid Hosting allows you to mix and match compute platforms to best suit your needs. Finding files that are modified or updated by you in the last few days for backup or recovery or simply synchronization. By default, php errors are logged to that file unless otherwise specified by your application. So as you can imagine, if your application is requiring upwards of 128M of memory just to load a single webpage it probably won’t load very quickly. Cloud FilesTM, powered by OpenStack®, provides easy-to-use online storage for files and media. While Rackspace originally contributed the code for Cloud Files “Swift” that became the OpenStack Object Storage, today there are over 170 companies and over 3,000 people that are involved in the OpenStack ecosystem.
It’s a great time to check out all the new features that we have added to Cloud Files for your next project. If you need more than 100 TB of data stored in Cloud Files, please contact us for special pricing. Oftentimes, when a customer complains of their site being defaced or infected with malware, we will investigate and discover that they are using a CMS such as WordPress. The maintenance will impact customers utilizing Cloud Servers, Cloud Files and Cloud Sites.
During the maintenance window, we will be performing an upgrade to our entire Cloud infrastructure.  Please note that throughout this time there will be no access to your Control Panel or the Cloud API. Multiple systems within our infrastructure, including internal support tools, will also be affected.
If you have any further questions concerning this maintenance, please do not hesitate to contact a member of our support team, via chat or via ticket.


Wherein session_name is the saved session name, your_user_name is your SSH login user name and your_password is the password. Linode is probably the cheapest VPS in all unmanaged hosting companies but it’s far from the worst.
They also have a very comprehensive documentation library that you could look up stuff in case you don’t know how to do something by yourself. The only down time I experienced was a power outage or something that lasted about 3 hours. I would recommend Linode to anyone who’s good at managing the hosting server themselves! In a managed hosting environment, your provider owns and is responsible for the data center, network, devices, operating system and application infrastructure components, providing a stable operating environment for your applications. Managed Hosting provides more value than colocation and dedicated hosting because it frees more of your IT personnel from mundane infrastructure related tasks, personnel that can now be reallocated to understanding and supporting your business more effectively. Managed Hosting also provides greater responsiveness than fully outsourced solutions because it emphasizes a flexible bottom-up approach to delivering value that puts you fully in control of your OS, application infrastructure and application. Securely store files in the cloud and access them anywhere via a virtual network drive on your desktop or on the web. I would appreciate it if you can click this link to be my referral so I earn a commission for your order. Make no mistake, and you would find them to be the most cost-effective solution AND the best supported cloud offer. You can find latest information, news, tips, deals and promo codes regarding the hosting industry and hosting companies. This article uses the Rackspace cloudservers™ hosting service to provide a concrete example of implementing sFlow monitoring in a public cloud. The private network is intended for inter-server communication and there are no usage charges. The firewall configurations were modified (changes shown in red) to implement packet sampling and allow sFlow datagrams to be received from the private network interface (eth1). Windows and Linux servers export standard metrics that link network and system performance and allow a wide variety of analysis applications to be used. With sFlow, data is continuously sent from the cloud servers to the sFlow analyzer, providing a real-time view of performance across the cloud. Polling breaks down in highly dynamic cloud environments where servers can appear and disappear.
Cloud Files integration with Akamai’s CDN allows you to serve your content globally, giving you high-speed delivery of content to your site and faster page loads for your site visitors. The growth of Cloud Files, now one of the largest storage platforms in the cloud, is giving us the economies of scale that allow us to reduce costs and pass savings to you. At present, Cloud Files is based on the OpenStack Object Storage Essex release which includes code contributions from a global community of developers, software companies, hardware vendors and service providers. Also, remember you can always contact Support to send us your data by mail using Bulk Import. The danger in using these packages, from a security standpoint, is that they are so common as to make a large target for malware writers. As a result of these infrastructure improvements, our ability to provide support will be limited until maintenance completion. And then you can click the saved session to start the pre-configured SSH session, thus don’t have to enter the host name and port every time you need to connect. I can’t do all the content myself so I constantly use article writing services to get the jobs done. Section the article well and title those sections well so readers can find something very very quickly.


Your IT organization manages your applications and maintains full control over the operating system and application infrastructure. In addition, Rackspace  Hosting also delivers a number of key services designed to keep your applications secure, stable and responsive to your changing business needs.
There is no learning curve; it works just like any other drive, drag and drop, copy and delete. With sFlow, cloud servers are automatically discovered and continuously monitored as soon as they are created. It's best to compile sflowtool from sources since the older pre-compiled version are missing decodes for newer sFlow structures. The php memory value is how much memory your application is requiring to load each webpage. With pay-as-you-grow pricing, you only pay for the amount of storage and outgoing bandwidth you actually use.
If you have any questions regarding Cloud Files, don’t hesitate to give me or my sales team a call. Combine this with their support for third-party add-ons and the rapid speed of development, and it’s easy to see how vulnerabilities can creep in. We do not expect this update to result in any downtime to the Rackspace Cloud production environment, only to the management tools and API.
Like, after you double click the PuTTY shortcut in Windows, it will automatically connect to the remote server AND supply the SSH user name as well as password so you don’t have to. For example, an article that yells and calls names (not necessarily so, just making a point). People attentions are very very short on the web and they generally hate large blocks of tedious texts. But if you can do the writing the way I described above, I’d still pay you a solid $xx even if you only wrote 300 words. Easily set up multiple drives that can be accessed from any desktop or on-the-go through a secure web interface. Store an unlimited number of files with an included 10GB per user and additional storage available on demand.
Files are updated as changes are made and are synced online as well as on teammate’s computers. The sFlow messages act as a server heartbeat, providing rapid notification when a server is deleted and stops sending sFlow.
I used to buy articles by words but later gave up on this approach because I found writers who charge by words isn’t quite good.
It’s rather long with tedious paragraphs and little section heading (even if there were, they were too short and non-informative).
Though it’s very much painful for me to manage the vps box myself, it’s a great learning experience after all and I did learn a lot!
Go offline and keep working; the files will update as soon as an Internet connection is established.
They are eager to help those who need tips to set up and harden their boxes against security breaches.
