are you aware of the best companies which provide apache solr AS A SERVICE? where i can simply upload (or edit via some web control panel) my index and config files for SOLR and simply start using it
i do not want to be breaking my head with any sort of server administration on tomcat
just update my index and config files... tell solr where to look for data to index (via data import handlers) and thats it just start using it
any sort of load balancing / mirrors would be like icing on the cake
price does not matter as its for mission critical apps
please do not suggest me to boot up my own servers on amazon or rackspace or xyz and then deploy solr on them and manage all the administration - because thats what i want to avoid in the first place completely
thanks in advance
I wanted to update this post from 2011 now that it's 2017! Today for folks looking for pure self service and simple Solr search we continue to recommend www.websolr.com. If you are looking for a managed complete Solr instances + some nice search analytics capability, then we've used SearchStax very successfully.
there is also this one:
http://www.opensolr.com/
Opensolr proposes 3 types of Solr instances :
CMS instances (WordPress, Drupal, Joomla, eZ Publish, Typo3)
API instance (RESTful Web service) with fully customizable configuration files
Web sites Crawler instances
There is a free account (i think it can be used actually only for test the platform), and the price for the other kind of account is cheap (4$/8$ a month for medium accounts)
(i didn't try it yet, but it seems promising)
If you use Drupal, there is also Midwestern Mac's Hosted Apache Solr service, which works with Drupal 6 and 7, and all the different Solr integration modules. (Disclaimer: I'm the owner of Midwestern Mac—let me know what you'd like to see and I'll try to make it happen!).
The company IndexDepot (www.indexdepot.com) offers a hosted Solr service. It's easy to use, because you log into an web interface to edit your configuration files. Special configurations fitting your requirements are negotiable, e. g. dedicated master/slave Solr servers.
You can try contacting Lucidworks with that question.
I heard they were working with Boomi on PaaS/Saas for their Lucidworks 1.4.
Although Boomi don't explicitly say that they support Solr, this webinar may suggest they were working with Lucidworks to include their Solr-based search engine in their portfolio.
Even if Lucidworks people don't provide SaaS, they're surely the right address to ask who does.
Good luck in your search and please get back to us with the information you manage to find...
EDIT 04/2012:
If I had to make that choice today, I'd seriously consider CloudBees (which has WebSolr plugin). It's a complete ALM & CI cloud framework for JVM-based languages, with loads of partner plugins (Jenkins, NewRelic, Sonar, MongoHQ, Cloudant, ...), many of them with free base options.
The most significant difference, when comparing with other SaaS/PaaS services, is that you can set up development environment and even deploy your app (on one node, of course) without even leaving your credit card details.
Just to expand horizons.
please do not suggest me to boot up my own servers on amazon or rackspace or xyz and then deploy solr
You can go with ready to use:
http://aws.amazon.com/cloudsearch.
Cloudsearch provides simple API.
And more and more hosted Elastic Search solutions appears recently. I think it's because of cloud ES nature (easy to maintain search cloud).
http://indexisto.com
http://qbox.io
But of course this is the matter of how sticky are you with SOLR.
These guys also so hosted Solr.
https://www.hosted-solr.com/?locale=en
They also have a custom extension that integrates Solr into TYPO3 CMS.
http://www.typo3-solr.com/en/home/
Take a look at our Fully Managed Solr Cloud Hosting, where we enable customers like you to not worry about managing and maintaining Solr infrastructure, but instead focus on building your application.
We offer shared clusters that caters to price conscious customers and dedicated nodes and dedicated clusters with white glove service for companies who want to completely offload search infrastructure and management.
We are a technology partner with AWS and depending upon the critical needs, can customize a hosted solr solution per our customers needs.
please do not suggest me to boot up my own servers on amazon or rackspace or xyz
and then deploy solr
You can try the below solr service provider, looks cheaper as well

Is it practical or wise to use Lagom in production without ConductR? The commercial licensing is putting me off. This framework looks like it could be pretty arduous to deploy and custom tooling for that can take a lot of effort to get right.
(disclaimer: I'm a Lightbend employee, currently core member of the Lagom team)
Edit (Nov 2018): Please refer to https://www.lagomframework.com/documentation/current/java/ProductionOverview.html#Running-Lagom-in-production for up to date information on this topic.
(original answer, Aug 2017)
A lot has changed in the Lightbend stack since this question was added over a year ago. For example: ConductR is now free to use in production for up to three nodes.
Also, the team behind ConductR is also working on providing tools to deploy a Lagom application on Kubernetes. The efforts on that front are very advanced and some of our sample apps can be deployed in Kubernetes already.
Your question is rather open-ended and so let's start with "it depends".
If
you're comfortable managing your scaling within the configuration of your Akka cluster,
your usage doesn't violate the open-source licensing terms of lagom, play and Akka, AND
you don't have sufficient cash flow to justify leveraging Lightbend's production suite,
then you arguably can deploy with a minimum of effort and custom tooling.
If those conditions don't hold, your options are to go elsewhere (e.g., Spring Cloud) or retain Lightbend. You may find going elsewhere has it's own cognitive load and/or commercial expense.
Hope that helps even 7 months later.
The other answers are higher level, but I can essentially say "yes." I'm currently deploying a Lagom service to be hosted on a Kubernetes cluster, and I'm not using ConductR or any of the commerically licensed components.
You will need to dig a little bit into some Play internals to start the service properly, and if you want to hook in with some other service locator you may need to implement one yourself, but it certainly isn't impossible and I think it's less effort on net.
Being honest it really worth to pay, because you got much more, good reporting dashboards, automatic cluster formation and what really cool is split brain resolver....
But sometimes agree when you are working on a project that don't have a lot of money, you can do some small tricks and get it work and may be then do all what really lucks or buy enterprise subscription.
So Lagom can be very easy being used without service discovery at all if you will delegate all to Kubernetes DNS or without Kubernetes just put load balancer before each service and use its address.
How this can works
Each lagom service that you have should be external service
Production run configuration should be mixed with
ConfigurationServiceLocatorComponents
Service that should communicate with another one should be started with extra parameter that tell lagom that this service is external one and can be communicated directly(all can be in JAVA_OPTS as for play application)
-Dlagom.services.your_service_name=http://k8s_service_name.default.svc.cluster.local:9000

We are going to use solr as our search server but as you know solr is based on java and apache server and our database is MSSQL and our webserver is IIS. Could you possible suggest me the best way to incorporate java apache asp.net and IIS?
Best
You cannot deploy Solr inside IIS because it requires a servlet container. Instead you can deploy solr in any one of the below servelt containers
Glassfish
JBoss
Jetty (default, included into solr package)
Resin
Tomcat
Weblogic
WebSphere
You can find the in-depth details about each deployment here SolrInstall
Then you can communicate with solr from .net using either one of these drivers(clients)
solrnet
SolrSharp
You dont need to worry about IIS at all.
https://bitnami.com/stack/solr
It's an installer. And Bitnami soooo rocks for doing this! Just tried a bunch of different things...
Using Web Platform Installer to install Zoo, which does Solr through IIS. It's bugged out.
Jetty doesn't install as a service
Tried running Tomcat 8 with their IIS connector (acts as a filter you can set an app to). Configuration was insane. Missing files from the connector.
Found that as my last search, and it's awesome!
This is how you should set up your application.
Host Solr in Tomcat.
Use DataImportHandler to feed data from MSSQL to Solr.
From your ASP application talk to the Solr via HTTP. (Write some helper classes for this)
Parse the JSON response using Newtonsoft.Json.Linq library.
The best practice is that you get the document IDs from Solr and fetch the other information from MSSQL.
I have configured this set up in a large e-commerce site and supported site search, search suggestions, search refinements (using facets), and lot of other complex lookups. It's working great and super fast.
Take a look at this one. They deploy java servlets under iis.

I'm trying to setup a server based on our needs for a new website. Basically, I need to build a website based on social engine, and according to the platform's requirements (found here: http://www.socialengine.net/support/documentation/article?q=152&question=SocialEngine-Requirements) it requires the webserver to be Apache based.
Now my issue comes with the addition of a web application that needs to be included in the site. The web application requires the server to be capable of Asynchronous Request Processing, and is currently only supported by Tomcat or GlassFish.
I found a couple tutorials such as this one http://www.serverwatch.com/tutorials/article.php/2203891/Integrating-Tomcat-with-Apache.htm that explain how to "integrate" Tomcat into Apache. Would a server running Tomcat alone be able to handle the applet needs as well as serve the Apache (assuming HTTP) needs from the Social Engine platform? Are there any hosting providers any of you would reccomend?
Although I've done alot of front end stuff before, this is the first time i have to deal with any of the back end details, so my knowledge of server side functionality is really garbage. Please let me know if I'm not asking the right questions.
Thanks
You wouldn't really be able to use Tomcat for both apps, since the other one needs PHP. It's pretty common to have both Tomcat and Apache running on the same server. You might want to look up more recent documentation on mixing them, even this but definitely have a look at mod_proxy_ajp.
What's the other application? It's a little tricky to set up Asynchronous Request Processing if you are new to server apps, but there is also a lot of documentation, so if you're game, you can probably figure it out OK. You might also want to see if that app would work with node.js (hosting info here)
If you want to set it all up yourself, you could get a virtual private server from Rackspace Cloud or similar host or get a shared host that has the required apps already set up, which would limit your ability to customize the environment and may require 2 hosting plans, but would be easier to set up. It also somewhat depends on if both apps need to be on the same machine for any reason and/or on the same domain.
A regular LAMP stack will run SE4 just fine, however, you will need to do some tuning to get the page loads under 3 seconds. You will want to remove any Apache modules that you aren't using with a2dismod. For instance, if you're not using any Ruby on the site, a2dismod ruby. This will help get memory usage under control. APC is a must.

ZooKeeper is a highly available coordination service for data centers. It originated in the Hadoop project. One can implement locking, fail over, leader election, group membership and other coordination issues on top of it.
Are there any alternatives to ZooKeeper? (free software of course)
I've looked extensively at Zookeeper/Curator, Eureka, etcd, and consul. Zookeeper/Curator and Eureka are in many ways the most polished and easiest to integrate if you are in the Java world. Etcd is pretty cool and very flexible, but It is really just a HA key store so you would have to write a lot of code to turn it into an opinionated service discovery system.
Consul is (to me) the best of both worlds. It is an opinionated service discovery system written on top of serf, using raft for cluster consensus and gossip for communication. It exposes the discovery / registration endpoints with a well documented REST api, and also allows you to discover services with DNS SRV records, and register services with configuration (i.e. so you can register a database or application you can't integrate a client with, or if you just want to keep your service discovery decoupled from your app)
I've written a blog post about consul where you can learn more and walk through my "try it out" demo
I've also discussed service discovery with etcd & docker if you want to see more about what that custom code might look like.
One last thing! etcd & consul are written in go, so maintaining them is much easier then java solutions like zookeeper. All you need is the consul / etcd binary. no dependencies, no linked libraries, no jvm.
There's a very promising alternative to ZooKeeper called etcd (github.com/coreos/etcd), written by CoreOS team. Unlike Doozerd, etcd is being actively developed.
Just discovered Accord (C) and OpenReplica/ConCoord (Python) which may be interesting solutions
[EDIT] The Hashicorp crew, of Vagrant and Packer fame, are cooking "a decentralized solution for service discovery and orchestration" called Serf.
[EDIT2] Hashicorp strikes again ! They just released Consul, built on top of Serf. The pitch: "a solution for service discovery and configuration, completely distributed, highly available, scalable to thousands of nodes and services across multiple datacenters".
Yes, there is also Doozerd (https://github.com/ha/doozerd). Take a good look at it, it's a nice, single binary distributed coordination service developed by Heroku. With bindings/libraries for java/python/ruby/node. Very easy to get started with and play around.
Take a look at Serf. There is a comparison vs Zookeeper here.
OpenReplica from my research group is a highly available FOSS coordination service for data centers. It can be used for implementing locking, fail over, leader election, group membership and other coordination services. It differs from ZooKeeper in two critical ways:
It uses an object-oriented API. This makes it much easier to write coordination services. Synchronization code for OpenReplica looks exactly like its textbook counterpart; there is no need to master a file and upcall-based API like in ZooKeeper and Chubby.
It enables dynamic membership updates to the replica set. There is no need for static configuration files. The system is integrated into DNS (authoritative, slave for OpenReplica, or Amazon Route 53).
We actively support the system, do not hesitate to let us know if you have further questions.
There's a project called Noah on github that looks interesting, it says that it's "loosely based on Apache ZooKeeper" https://github.com/lusis/Noah with REST support being a key feature (ZK has this as a contrib/option rather than built in).
There are different tools that optimize for different engineering trade-offs.
ZooKeeper Scales marginally for reads; writes with many observers can be slow. It is proven and has a sizable community.
Accord Seems interesting for write-intensive uses, however typical use-cases already have domain-specific solutions (i.e., logging, telemetry).
The others are somewhat interesting but generally unproven. Don't get this wrong if intended for production usage.
I'd found this comparison of Zookeeper, etcd and Doozer:
http://devo.ps/blog/zookeeper-vs-doozer-vs-etcd/
Serf (serfdom.io) is also a nice solution as it is simple! But you must consider, SERF is just a cluster-manager which enables you to send custom events to all cluster nodes. Thats nice, but you have to write your own shell scripts (aka events).
See this example: "https://www.digitalocean.com/community/articles/how-to-set-up-a-serf-cluster-on-several-ubuntu-vps"
The advantage is, you're getting a very simple cluster-manager and you're able to combine this with your favorite configuration, deployment or continuous integration tool.
It seems Corosync is also like ZooKeeper.
I know this post is quite old, but someone who is looking at all possible alternatives I would also like to suggest JGroups library which is mature enough to be used in production environment. I have used it successfully in one of my projects mainly for distributed coordination and to share messages between cluster. It also support AWS support in addition to its flexible architecture where you can customize its stack to get what you need. I suggest you to have a look at it
We are a very small mobile company (building an application for the iphone) and we are currently considering hosting services. We are currently leaning towards Amazon's hosting/web services. Accordingly, I have some questions:
1) Can I create an admin account on AWS and assign user accounts to developers that should have access to most (but not all) features.
2) Do we need to learn / use AWS APIs in the development of our product? I don't like the
idea of having to create hooks into a hosting service.
3) It looks like the pricing for AWS scales with usage. So, since we are in development and have only developers accessing the server right now, am I right that the cost will be quite low if anything?
4) How does AWS do version management? We have several developers scattered throughout the country. Each will need to checkout the the recent build from the server for development
on his local box. Basically, something like SVN. Is this possible?
5) I am guessing we need something like a dev, svn, and production server? Is this right? If so, how do I set this up and find out the associated costs?
6) We are considering a few database options, among them NoSQL and Neo4j - will we be able to do this using AWS? The server language will be Java.
Thanks for your time.
To answer your questions:
Yes, kind of. There is Identity and Access Management offered by AWS, but it's not the easiest solution to use. Having said that, it can allow you to lock down some of the access activities on an account so that you have some control over your users. I would say that AWS is still very much a single-user environment for server administrators.
You could get away using only the management console. Your use of scripting may only be required if you want to run batch or periodic activities (eg. take a snapshot of all machines at 2am every night).
Costs for EC2 are low, especially for the Micro machine sizes. But keep in mind that the idea of cloud computing is the availability of on-demand resources for short term use. If you run dev machines needlessly over night then you will still be paying! And if someone launches an Extra Large machine (or 30 machine instances) then you will suddenly find yourself with bigger bills than expected.
(5. and 6. as well) Amazon EC2 is really about issuing you the boxes. What you do thereafter is fully up to you. You can create snapshots daily of your machines, you can deploy SVN and noSQL etc. etc.
I've been seriously into EC2 for a while now, and lots of companies are starting to look at the idea you propose. There are benefits to giving staff on-demand compute power, without having to manage any infrastructure in-house. But I will re-iterate my first point that EC2 is very much a single-user, server administration environment, which doesn't lend itself to being used as a dev playground without additional tools. (Or at least it becomes a challenging task if you have several devs spread around in your company).
I own a business that helps companies use EC2 for dev/lab/playground type of environments. I won't directly flog it here, but will show a quick demo we just put on DropBox: http://dl.dropbox.com/u/16347737/RequestEC2Machines.html Feel free to request a machine to see how adding process to EC2 can help meet your goals.
I run/develop a website using Amazon EC2 & SimpleDB and I have some comments for you on your questions
Hi.
We are a very small mobile company (building an application for the iphone) and we are currently considering hosting services. We are currently leaning towards Amazon's hosting/web services. Accordingly, I have some questions:
1) Can I create an admin account on
AWS and assign user accounts to
developers that should have access to
most (but not all) features.
In my experience, there doesn't seem to be a direct correspondence between Amazon users and users on a single instance. An instance's root account is connected to the amazon account indirectly through a key pair. Although, I must say that I haven't explored this question in detail.
2) Do we need to learn / use AWS APIs in the development of our product? I don't like the > idea of having to create hooks into a hosting service.
I manage everything through their web console and Eclipse IDE plugins. I've never had to touch the API yet for development and deployment.
3) It looks like the pricing for AWS scales with usage. So, since we are in
development and have only developers accessing the server right now, am
I right that the cost will be quite low if anything?
Micro instances cost the lowest and the cost is pretty good if you're just starting an instance for a couple of hours and then stopping it. I never think twice about starting a micro instance to try out something new
4) How does AWS do version management? We have several developers
scattered throughout the country. Each will need to checkout the the recent
build from the server for development on his local box. Basically, something like SVN.
Is this possible?
I haven't seen this feature being offered directly by Amazon. You can of course keep an instance always on for your repository with backups
5) I am guessing we need something like a dev, svn, and production server?
Is this right? If so, how do I set this up and find out the associated costs?
EC Pricing - http://aws.amazon.com/ec2/pricing/
Amazon Simple Monthly Calculator - http://calculator.s3.amazonaws.com/calc5.html
6) We are considering a few database options, among them NoSQL and Neo4j -
will we be able to do this using AWS? The server language will be Java.
Amazon instances can be what you want them to be, hence you can either use a pre-configured ami to launch an instance or start off with a bare bones Ubuntu Server or Windows Server e.g. and build a system with what you want. You can then save the snapshot of that system to launch more in the future or to re-launch if your instance crashes
