ارشيف التخزين السحابي مفتوح على الموقع.

A careful Egyptian-style pronunciation would be:

arshīf et-takhzīn es-saḥābi maftūḥ ʿala el-mowʔeʿ

A few useful notes:

• التخزين is pronounced et-takhzīn because ت is a sun letter
• السحابي is pronounced es-saḥābi because س is also a sun letter
• الموقع is often pronounced el-mowʔeʿ in Egypt, with ق becoming a glottal stop

It is understandable in Egyptian Arabic, but it sounds formal and quite close to Modern Standard Arabic, especially because of the technical wording.

In everyday Egyptian speech, people might say something a bit more conversational, such as:

• الأرشيف بتاع التخزين السحابي مفتوح على الموقع
• or even mix in English tech vocabulary

So the sentence is not wrong, but it is more formal/technical than casual spoken Egyptian.

Because this is an iḍāfa construction, often called a noun-of-noun structure.

أرشيف التخزين السحابي literally means:

• archive of the cloud storage

In Arabic, the first noun in an iḍāfa usually does not take الـ. The whole phrase becomes definite because the second part is definite:

• التخزين السحابي = the cloud storage

So:

• أرشيف التخزين السحابي = the cloud storage archive

It is a noun + adjective phrase:

• التخزين = storage
• السحابي = cloud / cloud-based

The adjective السحابي describes التخزين, so it must agree with it:

• both are masculine
• both are singular
• both are definite

That is why it is التخزين السحابي, not just التخزين سحابي.

Because the main noun أرشيف is masculine singular.

The word مفتوح is the predicate adjective, and it agrees with the subject:

• أرشيف → masculine singular
• so the adjective is مفتوح

If the subject were feminine singular, you would use مفتوحة instead.

Arabic usually does not use a present-tense word for is/are in sentences like this.

So:

• أرشيف التخزين السحابي مفتوح literally looks like:
• the cloud storage archive open

But it means:

• The cloud storage archive is open

This is a normal nominal sentence in Arabic.

Here it most likely means open, available, or accessible, not physically open like a door.

In technical or online contexts, مفتوح can mean:

• available for users
• accessible
• enabled
• publicly open

So in this sentence, it probably means the archive can be accessed on the site.

Because على is commonly used with websites, pages, and platforms to mean on.

So:

• على الموقع = on the website

This is very natural in Arabic for online content.

Sometimes you may also see في الموقع, but that can feel more like:

• in the site
• within the site
• or at the site

For content appearing online, على الموقع is very common.

The sentence has three main parts:

1. أرشيف التخزين السحابي
   the subject noun phrase

2. مفتوح
   the predicate adjective

3. على الموقع
   a prepositional phrase giving location/context

So the overall pattern is:

[subject] + [predicate] + [prepositional phrase]

Yes. In pronunciation, الـ changes before sun letters.

In this sentence:

• التخزين is pronounced et-takhzīn
• السحابي is pronounced es-saḥābi

That happens because ت and س are sun letters, so the l sound of الـ is absorbed.

But:

• الموقع is pronounced el-mowʔeʿ

because م is a moon letter, so the l sound stays.

The spelling does not change, only the pronunciation does.
